I'll be more actively handling spam as well, but it's clear that we need additional people for global instance moderation. I'll prioritize this. I'd like to delegate instance administration as much as possible and fully focus on code

Said before (forgive me if you planned on replying to it), but is spam filtering (and similar issues related to moderation/federation) something you're planning or?

The current spam is rudimentary so I don't think false positives are a reason for no filtering at all, particularly if existing users are not scanned the same way. If mods can un-delete false positive threads/comments made by new accounts surely it'd be less work than manually removing spambot stuff (even if it were per-user). Especially if manual spam removal means that people still see the spam.

EDIT: Also clicking on one of the new spam accounts, 13 minutes old with 6 threads (and that was posted almost immediately with the rest posted within the span of 3 minutes).
