@sun The goal is to completely sever s2s communication with pedophiles (currently 66 domains and 15 actors not covered by those domains, plus 4 more complicit actors for whom I don't also remove media yet) beyond what is necessary to not break thread contexts and to be able to send a woodchipper or some other repellent. This means no likes/repeats/reacts and follows both in and out. The former could easily be filtered by checking whether the `to` field contains the actor meeting criteria; however, Pleroma's pipeline is faulty in a way that it fetches the referenced object before MRF filtering activity referencing it. This can be solved with a single line that puts MRF filter earlier in handle_incoming. Overall it was pretty effective, but pisskey's reacts don't contain any `to` fields in their first form at all, meaning there's simply no way to filter them without fetching the object. So I just decided to kilt them in entirety.
