@ojou @AmkiTakk
We do block some instances, silence some & reject media from some.
The mod team is currently discussing the general approach we'll take to federating with other instances, and I want to make that approach public when we've all agreed on it.
We probably won't publish the full block list at any time soon, although that's up for discussion too.
For now, I'm happy to answer answer any questions about blocks or limits on specific instances.
@Satsuma @admin it is still a thing afaik although i’m not admin of a v4 instance to be able to check; look in administration > site settings, near the bottom
