This is exactly what happened to voat. First step was signing up fake racist/psycho rightwinger accounts. Second step was troll pedos posting and getting the sites donations and financial support cut off for CP and drugs. Third step was inserting drama and paranoia with accusations about every other mod secretly being an infiltrator. Fourth step is denial of service attacks to stretch finances even further. Final step, with half the userbase already giving up on things or accusing each other of being a pedo and/or an SRS infiltrator, and no money to hire mods or admins to help, was to massively increase activity from all the the fake racist accounts, and simultaneously invite stormfronters and pol in. After that, voat wasn't much more than a smoldering wasteland filled with a few tired dregs of some of the first banned subreddits. And a bunch of accounts that almost never post unless there's been a major banning on reddit, and then when they do, its with "GUYS WE NEED TO SPAM RACIST MEMES OR THE JEWS WILL TURN US INTO REDDIT."

They'll probably try some variation of this here. Who "they" are, I have no idea. It could be anyone from political activists to some TLA to reddit itself(or a troll firm they hired)
