I got auto-banned after commenting on a reddit post because the bot searched my entire post history and found I had commented on NSFW threads in the past! The extra fun part was that I really hadn’t. The NSFW threads were from subs that had turned that flag on for all posts out of protest for Reddit’s closed API debacle. In short, exactly as you describe. Intending to quash the revolution.
If AI was reliable, maybe. MAYBE. But guess what? It turns out that “advanced autocomplete” does a shitty job of most things, and I bet false positives will be numerous.
