AI Corporations Stealing Data from Lemmy Instances; Consent is the New Battleground

Post date: April 9, 2026 · Discovered: April 17, 2026 · 3 posts, 119 comments

Large tech entities are aggressively scraping user data from decentralized platforms like Lemmy while sensitive, private interactions are leaking from NSFW AI services.

The fight boils down to legality and ownership. One side claims data on federated sites is inherently 'public,' arguing API shutdowns forced this shift, as stated by 'anarchiddy.' Others warn this scraping constitutes system degradation, potentially actionable as 'trespass to chattels,' a point raised by 'litchralee.' A critical focus emerged on consent: 'pulsewidth' argued that deriving pornographic material from real people’s photos is fundamentally illegal, unlike artistic work based on self-generated content.

The consensus is that unauthorized harvesting of private data for proprietary AI training is a severe privacy breach. The deepest fault line is between those who view federated data as free-for-all public domain and those demanding platform operators implement immediate anti-scraping defenses, as 'rekabis' insists.
