They've shut down their forum entirely for the next 3 days apparently. With Agora's recent revelation about tor vulnerabilities and nucleus having been hacked very recently i wouldn't be surprised if they pull a quick exit.
There are other ways of dealing with spammers than shutting down the whole forum, it doesn't really seem to be appropriate.
Stay safe
They'd be daft to pull an exit now when the mother load is about to drop in terms of new users and therefore revenue to the site.
