I do intend to send them a DM soon, but defederation happened first so we don’t have to deal with the harassment accounts and so users don’t have to be exposed to all the abuse.

AFAIK the only active admin (who is also the main admin account) was already instance banned from Blahaj for transphobia - so there wasn’t an easy way to talk to the admin in the first place … (at least not from an account on a Blahaj instance)

Defederation is not punishment, nor is it permanent. It is a reaction of self defense and can be reversed later.
