Oh fuck, it's not always easy to spot pussy instances...
At least Poast has a custom favicum, so it's easy to see which ones are using instances that shadowban me, but Mastodong.Soycialist is using the default Mastodong favicum (because of course), so it's harder to spot at first sight,
Well, you can change it, but it'll revert right back to the default favicum as soon as you update the soyware.
