@jerry @simonzerafa @scott Pleroma has exposed instance blocks in the API by default for a long time now

and honestly it's kind of required. If a server blocks you, you should want to add a reciprocal block to make sure you don't fetch any posts from them either. @sun went through this problem a while ago and had to write a script to automate reciprocal blocks but we should probably integrate functionality that does it automatically... though it would only work for other Pleroma instances right now unless a standard is developed
