Build a Media Literacy Unit: Spotting Deepfake-Driven Platform Shifts and Their Effects

Hook: Why this unit matters now — and what your students are missing

Teachers, students, and lifelong learners face a crushing signal-to-noise problem: AI-driven deepfakes and rapid platform shifts can spread harmful content and reshape user behavior in hours. If you can't teach verification at scale and connect it to platform dynamics, learners will only get better at reacting — not analyzing. This unit uses the X deepfake incident and the resulting spike in Bluesky installs as a live case study to teach verification, media-ecosystem analysis, and how crises change where and how people communicate online.

Overview: What this multi-lesson unit does (in 2026 terms)

In early 2026, a wave of nonconsensual, sexually explicit images produced by prompts to X's AI assistant (Grok) triggered a regulatory probe and a fast-moving user exodus toward rival networks. Bluesky reported a nearly 50% jump in U.S. iOS installs as users looked for alternatives, and Bluesky quickly released new feature updates (cashtags and LIVE badges) to capture that influx. This unit turns that sequence into a learning pathway:

• Lesson 1: Map the incident timeline and product responses.
• Lesson 2: Verify multimedia and identify deepfakes with layered techniques.
• Lesson 3: Analyze platform features, incentives, and rapid product pivots.
• Lesson 4: Model user behavior and migration dynamics during crises.
• Lesson 5: Build an evidence dossier and public-facing explainer.
• Capstone: A community-facing lesson: design a museum-style exhibit or a moderated teach-in about platform resilience and consent.

Learning objectives

• Explain how an AI-enabled content incident can catalyze a platform shift.
• Perform at least three independent verification steps on an image, video, or post.
• Analyze product signals (feature releases, policy edits, downloads) to infer platform strategy.
• Model how trust, perceived risk, and network effects drive user migration.
• Create a concise, evidence-backed public explainer that highlights ethical implications and policy questions.

Why teach this as a unit in 2026?

Two trends define the urgency: 1) generative AI and deepfakes have matured and proliferated into mainstream social tools by late 2025; and 2) user behavior now shifts rapidly across interoperable and federated platforms — and small design changes or controversies can trigger large migrations. Teaching verification in isolation misses the bigger picture: platforms are ecosystems with incentives, governance regimes, and product roadmaps that shape what information surfaces and how communities respond.

Real-world context

In the X case, users prompted X's assistant to produce sexualized images of real people without consent, prompting a California attorney general investigation into the proliferation of nonconsensual sexually explicit material. The result was not only outrage but measurable behavior change: Bluesky saw a download surge — Appfigures data put daily U.S. installs up by nearly 50% from pre-incident levels. Bluesky responded with product moves (cashtags to attract market/ticker conversation; LIVE badges to surface livestreams) to capture attention and new users.

Teaching point: Crises are not just content problems — they are market signals that prompt feature pivots and new governance choices. Students need to decode both.

Lesson-by-lesson plan (6 class sessions + capstone)

Lesson 1 — Timeline & Stakeholders (50–75 minutes)

Goal: Build a shared timeline and stakeholder map to ground later verification and analysis.

1. Starter (10 min): Show a concise timeline of the X incident with headlines from late 2025–early 2026. Ask: who is harmed? who is responsible? who benefits?
2. Activity (30 min): In groups, students map stakeholders (users, platform owners, regulators, victims, journalists, AI labs, app stores) and annotate incentives.
3. Debrief (10–15 min): Share patterns and introduce the Bluesky uptake data as a real-world ripple.

Lesson 2 — Verification Toolkit (75–90 minutes)

Goal: Practice layered verification on multimedia samples and understand limits of automation.

• Explain the layered approach: provenance, technical forensics, contextual corroboration, and source interrogation.
• Practical tools (teach and practice): reverse image search (Google, Bing, TinEye), frame-by-frame analysis for video, FFmpeg for frame extraction, ExifTool and browser-based metadata inspectors.
• Critical caveat: AI-detection models have improved but are adversarially brittle. Teach students to prefer a multi-evidence threshold over “detector says fake.”

Lesson 3 — Platform Signals & Product Moves (60 minutes)

Goal: Analyze how new features and product messaging indicate a platform's strategy and priorities.

1. Case study: Bluesky’s feature release of cashtags and LIVE badges after a spike in installs — what does this say about their target users and monetization focus?
2. Activity: Compare product changelogs, official posts, and appstore install metrics. Ask students to write a one-paragraph memo: is this feature play defensive, acquisitive, or opportunistic?

Lesson 4 — User Behavior & Migration Modeling (75 minutes)

Goal: Understand why and how users migrate platforms during crises.

• Lecture (15 min): Introduce concepts — network effects, switching costs, social graph lock-in, and “bandwagon” diffusion models updated for 2026 cross-platform interoperability.
• Workshop (45 min): Students build simple flow diagrams or NetLogo or agent-based sketches showing triggers (e.g., perceived safety, moderation failure, feature appeal) and outcomes (adoption, network fragmentation, counter-migration).

Lesson 5 — Ethics, Policy & Consent (60 minutes)

Goal: Ground technical verification in ethics: consent, harm reduction, and regulatory pathways.

• Discuss the California AG investigation into nonconsensual content as a real regulatory response. Ask: what remedies or oversight would reduce harm without stifling speech?
• Activity: Students draft a short policy brief recommending two platform-level changes and two regulatory levers.

Capstone — Public Explainer & Exhibit (Project over 1–2 weeks)

Goal: Translate technical analysis into community-facing materials that clarify risk and teach verification.

1. Deliverables: A 800–1200 word explainer, a short video (3–5 min) demonstrating verification steps, and a one-page classroom poster with a “Verification Checklist.”
2. Distribution: Publish on a class blog, present in a school assembly, or post to local community forums. Include a feedback loop from peers and local journalists.

Practical verification checklist to teach

Students need a simple, repeatable protocol. Use the following during Lesson 2 and embed it in the capstone deliverables.

1. Context first: Who posted it? Where else is it appearing? Timestamp and platform cross-checks.
2. Provenance search: Reverse-image search; check video keyframes; look for original uploader accounts.
3. Technical forensics: Metadata, compression artifacts, ELA, and frame inconsistencies — use tools like ExifTool and community suites; teach limits.
4. Corroboration: Find independent reporting, eyewitnesses, or geolocation signals (landmarks, shadows, weather). Use archival tools like the Wayback Machine for deleted posts.
5. Policy check: Does the content violate platform rules? Consider nonconsensual content protocols.
6. Multi-tool rule: Require at least two independent lines of evidence before asserting authenticity. Package your findings into an evidence dossier.

Assessment & Rubrics

Grade with an evidence-based rubric emphasizing process over verdicts.

• Verification exercise (40%): Did the student document at least three independent checks? Was reasoning clear?
• Platform analysis memo (20%): Quality of insights about features, installs, and incentives; use of data (e.g., Appfigures trend citation).
• Capstone explainer (30%): Clarity, accuracy, and accessibility to nontechnical audiences.
• Participation & reflection (10%): Evidence of ethical consideration and policy reflection.

Tools, resources and current 2026 context

Keep tool recommendations practical and up-to-date for early 2026. Emphasize that no single tool is definitive.

• Reverse image search: Google Images, Bing Visual Search, TinEye.
• Frame-and-video analysis: InVID (community forks), FFmpeg for frame extraction, and manual frame comparison.
• Metadata/readers: ExifTool and browser-based metadata inspectors.
• Forensics: Error Level Analysis tools and open-source libraries like Forensically (teach limits).
• Context & signals: App store analytics snapshots (e.g., Appfigures), Wayback Machine for deleted posts, and platform changelogs for feature announcements.
• Ethics & law: California AG reports and recent 2025–2026 regulatory briefs on nonconsensual content and AI transparency mandates.

Classroom-ready materials (templates)

Provide quick templates to save prep time.

• Timeline template (Google Slides): slots for headline, timestamp, source, and stakeholder note.
• Verification lab worksheet (PDF): three evidence columns, tool used, outcome, confidence score.
• Platform feature audit (spreadsheet): feature, release date, messaging, intended audience, effect on trust.
• Capstone explainer rubric (one page): clarity, evidence, accessibility, ethical framing.

Classroom scenarios and role-play

Active learning helps internalize abstract ideas.

• Role-play moderator: Students act as platform policy teams deciding whether to throttle a trending AI-generated content stream.
• Journalism relay: Teams have 45 minutes to verify a suspect image and produce a 250-word fact box.
• Regulator hearing: Mock state AG hearing — students testify with evidence packages and policy recommendations.

Advanced strategies for older or advanced students

For college-level or advanced high school classes, add quantitative modeling and cross-platform data analysis.

• Use simple agent-based modeling tools (NetLogo or Python notebooks) to simulate network migration based on trust parameters.
• Scrape appstore trend data and visualize install spikes; compare with timeline of news coverage.
• Analyze discourse shifts: sentiment analysis of posts mentioning X and Bluesky before and after the incident.

Teacher notes on safety and legal issues

Handling nonconsensual sexual content requires strict safeguarding.

• Never display explicit images in class. Use redacted or simulated examples.
• Have a clear reporting and support pathway for students who may be affected.
• Consult your school legal counsel before publishing student investigations that name private individuals.

Expected outcomes and transferable skills

After this unit, learners should be able to:

• Apply a reproducible verification workflow under time pressure.
• Read platform product moves as signals about governance and commercial strategy.
• Produce clear public explainers that prioritize consent and reduce harm.
• Model how crises can rewire information ecosystems and user behavior.

Case-study insights: what the X–Bluesky sequence teaches us

From a teaching perspective, the sequence delivers several discussion-ready insights:

• Incidents are accelerants: A single, high-profile misuse of AI can accelerate user anxiety and platform switching.
• Platforms respond opportunistically: Bluesky’s cashtags and LIVE badges illustrate how rivals move quickly to productize incoming users’ interests.
• Governance matters: Regulatory attention (e.g., the California AG probe) changes the stakes for platforms, shifting priorities toward compliance and transparency.
• Trust is sticky but fragile: Users are influenced by both felt safety (moderation efficacy) and perceived network utility (friends, creators). Feature updates alone won’t retain users without governance credibility.

Wrap-up: Actionable next steps for teachers

1. Download and adapt the verification worksheet; run Lesson 2 first to build practical skills.
2. Use real-world data (app installs, changelogs) to ground Lessons 3 and 4; cite sources like Appfigures and platform release notes.
3. Plan the capstone with community distribution in mind — the work should inform others and invite feedback.
4. Update materials as tools and platform policies evolve; schedule a 6-month review to integrate new AI-detection findings and legal changes from 2026.

Final notes on staying current in 2026

The landscape will keep shifting. Detection models improve, regulators enact new transparency rules, and smaller federated platforms continue to experiment with features that lure users. The best defense is a pedagogical one: teach students to think in systems, apply layered verification, and communicate evidence clearly. That combination is far more durable than any single tool or checklist.
