Valve takes aim at Counter Strike Gambling

An anonymous reader writes: Game maker Valve is threatening to shut down sites dedicated to gambling with add-ons to its popular Counter Strike game. On Thursday the company sent cease and desist letters to 23 sites, demanding that gambling operations be stopped, and that the sites had 10 days to comply. The row revolves around the software overlays that change the appearance of the characters people play in Counter Strike: Global Offensive (CSGO) and the weapons and other virtual items. Last week the company reiterated that its user agreements ban external sites from asking users to connect their Steam accounts in order to trade items for real money. The company added that it would use "all available remedies" against sites that did not stop players using virtual goods to gamble.
