Probably ineffective. 'Mins would know more but I don’t think they’re botting up thousands of accounts an hour. They likely spend more time finding posts to ragebait and gleefully typing out said bait than signing up a new account. It’d also need to be a security measure implemented across instance which is difficult as some of the shards are already very slow to update and the front end has a lot of customization on it.

Dunno.
