Ok for 2018, my idea is as such
Basically the premise is that spooky scary mod has escaped and the mods are helpless to stop him. He is a bot and is going around with a ban hammer and randomly banning people in fast moving threads. Of course this can only occur in large boards. His bans will read, "user was banned by spooky scary mod(or anything in between)" or anything along those lines. Even saying that Hiro did the ban might be a bit fun.
4chan users will then be given an option to either endorse the ban or repeal the ban. After a certain number of bans or repeals have been made, the user would either be given a 1 hour ban or those endorsing him will be given a 15 minute ban.
Problem is that I think people would just start endorsing all the bans.
But then again, I do think that this
>>5700 idea, is a good one
