We already have a filter to change stupid characters words in to even dumber words.
But what if we take it a step further?
My suggestion, is if someone types "lol" or any form of it, like lulz, or "umadbro?" or things like that, that they will suddenly explode with the force of 300% traps skill TNT.
This should help keep people from being random trolls, and at least disallow them to troll with that.
