Or maybe a cryptocurrency forum? 
They like to mix things, so maybe they will take a break and move on some exchange next.
Now would be the best time to improve security and privacy for any crypto service.
A forum?. Well, to be honest, I wouldn't be surprised if they point out a cryptocurrency forum one day. The way theymos has acted and managed BTT since January (although logically he made those decisions before) of this year is a telling clue and something that should make all users think about how things could be. And it is something whose solution is not simple.
It is not as easy as "moving" the forum to the Darknet, Tor and .onion is not the solution, since part of the traffic always comes from the clearnet and the "technical" issues, although simple, would make many users decide not to enter to the forum. The (possible) solution would be a decentralized software for forums, something similar to Mastodon (although its servers, called instances, are centralized) but focused on forums, and as far as I know there is no software of that type available.
Sorry, I read this post while checking the thread but forgot to reply to you.
