AIDS Simulator, Asset Flip Simulator, ISIS Simulator and Triggering Simulator have all been pulled from the Steam storefront by Valve.

Twitter user @robotbrush (below) first pointed out that the storefronts had been removed, and Steam Tracker shows that they are no longer on the platform either.

The launch of these games on the very day that Valve revealed its changes in content policy is a damning reminder of why the company needs to be taking more care as to what appears on its storefront, but fair play to the Washington-based PC giant for being proactive in this regard.

i mean, obviously volvo wants to let LITERALLY EVERYTHING onto steam ... that's why they just booted this particular "dev's" entire catalogue off steam ... pic.twitter.com/YEWPVLv5s6

Furthermore, the company's VR of marketing Doug Lombardi spoke to VentureBeat to clarify just what Valve meant by 'trolling' in relation to games that weren't allowed on the platform.

In relation to school shooting title Active Shooter, the marketing man said: "We rejected Active Shooter because it was a troll, designed to do nothing but generate outrage and cause conflict through its existence.

"In addition, the developer had been involved in numerous misrepresentations, copyright violations, and customer abuses. There are no second chances for Active Shooter, or its developers. And to be explicit, while the developer behind it was also a troll, we'd reject Active Shooter if it had been submitted by any other developer."

Valve revealed new content policy guidelines yesterday, saying it was going to take an even more laid-back approach to curation. This saw a mixed reaction from the industry; some called the firm out for what they saw as a lack of responsibility, while others saw it as the PC giant behind "damned if it does, damned if it doesn't".
