I think this board is being used for a lot of things, AI learning being one.
I also think some of the repeat shitposters that are recognizable shitpost to break the tedium, since perhaps they've been assigned here to monitor, and occasionally give an "anonymous nudge".
After all, if it WAS leaking "classified " info that also can be inferred from open source yet we haven't organically discovered it yet, nobody would know if one of the agents posted it anonymously.
