I once helped nuked a user who was a persistent sexual harasser with access to multiple /16 ranges - but their device config (browser and etc.) was unique to users of the service in question, so we just hellbanned that. (apologies for the level of vague here but I don't believe it's fair to anybody else involved to be less vague - including the user in question, who seemed relatively young and I hope has grown up since)
