@nmtake @fediverse >Akkoma is currently leading in this regard with their MRF feature, which allows administrators to write arbitrary polices to rewrite or delete messages
Yeah, bub, about that: https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/lib/pleroma/web/activity_pub/mrf.ex#L67
You're not allowed to reject or mangle activities of specific types in your own policies, and said change was introduced for no reason other than spite. Pleroma, which Akkoma rips off, has no such restrictions.
