Nothing stopping them, except, you know, the law… They can certainly display content that was not marked for public display. They will then proceed to get sued out of existence… If they do this automatically I’ll just privately post a music file with copyright protected music. Which is perfectly fine to do if it is indeed hidden from everyone. If they then publicly post it that’s on them and now I get to see the Music Industry fight the Zuck :D
Well, they could do that regardless of whether they’re running an ActivityPub service. Nothing’s stopping them from a technical viewpoint
