Ban face campers/campers/tunnelers!

I doubt they'll ever ban for something they've repeatedly stated on stream is not bannable. 
Instead of hoping for that, you should start working on how to counter. If running in SWF make sure your team don't make overly altruistic sacrifices and just get gens done, unless they can coordinate a multi player save (and someones running BT), just hang there and waste the killers time. If you run solo, run kindred so other players know you got leather daddy up in your face or flail like nuts in stage 1 so they know to stay away.

Stop feeding campers. If you feed them, then it just shows them their strategy works. If instead everyone does the smart thing and the killer consistantly only gets 1k and low BP it might make them change up their playstyle or worst case they'll keep doing what they do and it'll suck for 1 survivor but the other 3 will have an easy game.
