When news broke last week regarding gambling centered around Valve’s Counter-Strike game, the company didn’t have much to say. Now, though, the company has said they’re going to start working to shut down those sites.

Valve’s Erik Johnson, one of the company’s”business development authorities” posted on the Steam website to explain. Johnson said that Valve “has no business relationships with any of those sites,” and that they never received any revenue from them.

The sites, he continues, work on two sets of information. The OpenID API allows users to prove they own their Steam accounts and the items within, and then the users disclose other information manually. Then, the sites create automated Steam accounts that make the same kind of queries a user account is able to.

Johnson says “using the OpenID API and making the same web calls as Steam users to run a gambling business is not allowed by our API nor our user agreements. We are going to start sending notices to these sites requesting they cease operations through Steam, and further pursue the matter as necessary.”

In what sounds like a mafia-esque warning, Johnson adds that “users should probably consider this information as they manage their in-game item inventory and trade activity.”

This sounds like a pretty soft response, but we’ll see how actively they pursue these sites. While Johnson says the company hasn’t ever received revenue from the gambling sites, it’s tougher to argue that the sites haven’t brought them money in some way, and it’s possible they could be a little lethargic about bringing justice down because of that. But at the very least, the silence has ended, and Valve is taking measures.
