I saw it a handful of days ago and put the entire instance on my client’s filter list because the person I saw was not smart and I didn’t have a good feeling.

Meant instance, said instant

Most of the fediverse runs on a blacklist, not a whitelist. This means that new instances are federated by default as a general rule, though content only travels through instances when it's requested by users in some way or another.

Blocking an instance is not much more work than banning a user, so in most cases it's not a huge problem to have to actively defederate from bad actors.

Red was removed, i.e. was federated last week but not this week. Green was added in the last week. The remaining few were federated and still are.

This is a diff of their instances page a from last week Friday to today.

I assume they're newer instances coming online and federating with all they can. I'll check back in another week.

I know the admin of at least one of them and they're definitely not on board with that shit.
