Hi Crazy apple,
the Steam-ID you posted is wrong - its actually STEAM_0:1:80645017 and therefore not the "real" zm_youssef_the_terminator ;-)
The person who insulted you is a fake person playing for a couple weeks now with youssefs name, so be careful when judging and always look at the ID (type status in console).
Nevertheless thank you for the request, he is gagged for 1 week now, due to previous gags and because his chatlog is full with further german insults.
