of course mastodon.art is blocking the white trans girls ..

>admins friendly with known problem instances

well first of all, who other instances federate with is none of your concern.
secondly, there would be no problems here if these girls were black.
The reason given for this block is complete BS. mastodon.art just wanted to come up with a reason to block donotsta.re, because the admins are white and transgender. that's the entire reason. maybe mastodon.art should just be honest and put that as the reason.
