Its just so people dont say "im making a mafia" Copyright precaution ^^.
Who copyrighted and when??

The skins are public, and teams like "russian mafia" and "mafia" are also public...
Maybe you want to close all other skins, set there "leaders of teams" and others cannot use it and make their own???
The protection is on CLANs names, CLANs tags, TEAMs names... (registered)
No any copyrights of skins and general teams, that are integrated...
There can be lots of mafias-teams, and players can use any skin they want...

So remove that "notifications"...
:ps: BTW you were not the first with "mafia"... If follow your views - you should then remove group at all, as 10 days before there was organized mafia and even registered...
