@Yelrix @cosmic79 don't care about eshenk this guy is a troller that hate people that can't talk english as their native language, he often offer them his sarcastic " hum what ? " or " Lol " as an answer
I prefered when he was banned, it was calm with no stupid useless topic, no stupid sarcasm to people that have difficulty in english, no complaint about " not realistic, for kid, not californiant themed , no this no that " mod and no low rate for them
this guy is the dumb hater xenophobist of 5mods.
I don't understand why he didn't been permanently banned ;S
