Damn. It has been more than 5 years since I last played counter strike. Didn't valve but a ban on all kind of betting related to csgo? I remember receiving an email from one of the sites where they said that users items were stuck because valve but a mass ban on all of their betting trade bot account. Even I remember reading somewhere that cases were also being a problem since it was some sort of gambling.
Well, there is nothing much to do. They will have to face the disadvantage of playing bad online instead of LAN.
They did, and it seemed like Valve was enforcing the gambling ban pretty strictly right after they released their announcement and near when sites like OPSkins were shut down for gambling-related activities, but there's a ton of skin-related CS:GO gambling sites again as they're not enforcing the rule as much anymore, though most people using skins to gamble are still aware that the risk is there that their skins could be lost at any time.
