Smurfs R.I.P via new suggestion

[Lambchops]

I do agree with that.

Tournament matches shouldn't allow smurfs, or the ladder for that matter.

Yes, I agree with the sentiment, perhaps some sort of registration of your "official" tournament or ladder name could be done. It would still have to be relying on the players' (and admins) knowlege of each other. Because how do you really know if someone is registering twice with different names?
