From GI.Biz: “Valve has said it will “not tolerate racist language between pro players in any form” after two separate incidents directed at Chinese teams during professional DOTA 2 matches.
Andrei “skem” Ong from Complexity Gaming was formally reprimanded by his team — receiving the maximum fine — for a racist comment he made towards Chinese team Royal Never Give Up during the DreamLeague tournament earlier this month.”
