gollark: I was referring to filtering "liches and other stuff necromancers stumble upon".
gollark: *Can* they actually filter that (EDIT: referring to "liches and other stuff necromancers stumble upon") in practice, given the whole "end to end encryption" thing, apart from somehow not letting those on the network?
gollark: SCP-2167 and the other demonics stuff (http://www.scp-wiki.net/a-brief-explanation-on-demonics) probably qualifies.
gollark: Yep, a few came.
