@p @dcc @sysrq As I said before, this is a non-issue unless you're trying to build up an echo chamber with minimal amount of discourse your clique disapproves of. Interaction-driven federation can only go that far as well, if you want discoverability, you're better off using relays, since Pleroma by default includes an instance-wide relay anyone can subscribe to. That's the same mindset I see among the self-proclaimed oldfags of SPC alumni, and the same mindset that contibuted to Akkoma that's inherently hostile to discoverability.
>FSE still processes them, even if it rejects them or turns them into Likes or something.
I was under the assumption that if an activity gets rejected by MRF, its referenced object never gets fetched to begin with. If that's true, ironically, by converting them into likes you're contributing to the perceived problem.
