Valve is currently facing a lawsuit from concerned parents about potential illegal gambling surrounding Counter Strike: Global Offensive. The main part of the problem is that there are no protections to prevent minors from participating; although the fact that wagering on professional games exists is also a point of contention.
A blog post on the Steam Community explains that Valve has no relationship with sites like CSGOlotto, and warned users to be keep an eye on their inventory.
Since then a number of gambling sites started leveraging the Steam trading system, and there’s been some false assumptions about our involvement with these sites. 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.
Community manager Erik Johnson also wrote that Valve will be asking these sites to stop working through Steam and will be taking the necessary measures to ensure they cease operations.
Valve’s statement is an attempt to distance itself from the issue at hand, which is likely to upset those who believe that the company should be doing more to resolve the problem. However, it is unlikely that the there will be anything done to the Community Marketplace in the short term.
