I told someone who was sharing their key in a group of four people on a server it wasn't allowed, i tried to be nice and warn them, but..

Their ID is 18414, if anybody is interested.
I've seen people share their key in a group of two, but four?
He kept claiming they are all brothers.
And he wasn't just opening new windows into the game, they all talked individually, and at the same time, and they had diffrent clan tags.
I may be a douchebag for telling them this in the first place, but yeah, it's up to you on that.
