Was witches.town one of the Instances where the admins block certain other instances? If so, can I talk to one of the mods privately?
@creatrixtiara if it's a general question Mastodon.social does too. Some servers are more vocal about blocking /silencing (two different ways to treat problematic servers).
Sometimes it seems that block is the only option, while it's not. Silence only lets you interact with people you mutually follow on there, and you tend to have to follow them first.
