Hacked Multiplayer server?

I was looking for a game to join and saw this (below); is it a hacked server? Odd multi-coloured lettering and look at the guys avatar - never seen anything like him before (weird orange head and scarred torso).

Didn't join just in case.

Am I right to be cautious? I recall playing with hacked players before the game was released properly (Characters with 2348234987239 health etc).

Let's block ads! (Why?)
