No, you're only half right. Jubilee is a no no for the mod but the tower you're totally safe. Jubilee is basically PVP, or the closest thing we have to that right now, so it's watched heavily. Tower is still PVE so they don't give a fuck if you cheat on it since it really only benefits you. I've been using the mod on the tower for a while now and still haven't gotten hit with a ban.
