Fedi admins, please switch off instant signups! ๐
You can do this at Preferences > Administration > Server Settings > Registrations > Who Can Sign Up, change to "approval required for signup", tick box marked "require a reason", save changes.
If you allow instant signups, you are opening your server to spammers, causing headaches for hundreds of other servers who all have to block your spammers. The latest wave of spam is *all* from servers that have instant signups!
@homegrown I keep wishing for a Mastodon feature (or better, some kind of plug-in functionality for admins to develop their own event listeners) that would automatically limit a server if it has open sign-ups.
@homegrown @ona why this option is not disabled by default in @Mastodon ? Its not the first spam wave caused by this
