sysadmin help filtering spam
@leo You should be able to filter e-mail domains from registration, that helps a little if you can see a pattern from the accounts trying to register. I would also recommend requiring a message during registration so you can at least filter out anyone who doesn't read your CoC or ToS. Additionally, I would recommend requiring administrator / moderator approval for registrations, that way even if you get a lot of registration applications, they won't immediately become accounts.
On my end, I went ahead and disabled registration altogether. You could do this and then still enable registration invites for administrators / moderators, then set up a 3rd party way of sending registrations so that spam bots don't just use the API or template HTML pages to fill out registration froms. Hope that all helps.
