Hugops to every other #mastoadmin having to deal with this spam wave. We have been fighting is on mastodon.social for days, and were forced to close registrations yesterday until we could emergency-deploy countermeasures.
Unfortunately, this made them realise they are other servers in the Fediverse to target.
If any admin needs help fighting this, please ping me either on the server admin discord, or directly here, and I will gladly help.
