This particular character was banned four times for inappropriate name - which , in fact, was just "Rooster" if I translate it to english.
Support told me that current system is like that - some number of reports (WITH NO MODERATION FROM BLIZZARD) and yer banned (almost instantly). Amazing.
So a group of dedicated people can just ban a player at will.
