If that weren't sketchy enough, Cassell and Martin were promoting CS:GO Lotto on their YouTube channels without disclosing the fact that they owned the site. In an effort to distance itself from the controversy Valve (CS: GO's publisher and developer) has recently stated that it has zero affiliation with any third-party skin gambling services. As Game Informer notes, these skins can go for thousands of dollars -- something that Gabe Newell (above) and Co. apparently don't see a penny of.

"We'd like to clarify that we have no business relationships with any of these sites. We have never received any revenue from them. And Steam does not have a system for turning in-game items into real world currency," a post on Steam says. The third-party sites work by essentially creating Steam accounts, having users link their accounts to the service and then, the sites trade items internally. That's forbidden by Steam's terms of service, according to Ars Technica.

Cassell was also recently involved with the controversy surrounding Machinima and paid, positive videos about the Xbox One as well. Last month, an amended complaint was filed against Cassell, Martin and Valve for allowing an illegal online gambling market to crop up surrounding in-game items.
