Back when SA lead the charge to get all of those jailbait subreddits kicked off of reddit, one of the things used as reasoning for the shutdown were supposed screencaps of private messages of r/jailbait regulars sharing CP. People on reddit at the time who protested the shutdown theorized that goons were sending each other their CP collection and screencapping it as a false flag of sorts.
Given what we know about SA now, and the fact that the Aatrek and Shmorky incidents occurred since then (as well as FAU hemming and hawing about banning some random D&D shithead who was literally caught torrenting CP, they might have been on to something.
