I went on #support and had a talk with skulfuk and culapou was here.

There's pretty much nothing to be done about it since it's not in the rules that you're not allowed to self-decap. So we'll have to do a private server to be able to ban self decapping noobs etc... thing is decap prize disappear when private servers crash so SkulFuk will try to look into it as soon as he can - he told me it's at the top of his "to do list".

Lets hope we can do this soon enough ;p
