You see that box looking thing? You copy + paste that and back space til there is just this one box that says [hf] and then post, and there is a space (Derp Pika)
OK I looked into this and blocking every single space character and invisible character is practically impossible. So screw it, regular spaces are blocked but that's it.
Note that posting "blank" messages over and over is still spamming so you will get kicked if you do it all the time.
