we're permanently silencing mastodon.blue since the admin's stance on moderation ("if an user from my instance offends you, you can just mute them") doesn't match up with our ideals and they choose to ignore toxic behavior originating from their users
you can still follow and interact with users on mastodon.blue, they just won't show up on the PTL
I'll have to write up and publish a list of suspended/silenced instances soon, there aren't that many though
