the game Active Shooter, which would have allowed the player to play as either a SWAT team member tasked to take down the shooter at a school shooting incident or as the shooter themselves, was an example of trolling, as he described it was "designed to do nothing but generate outrage and cause conflict through its existence". While Active Shooter had been removed from Steam prior to Valve issuing this policy statement under the reasoning that the development had abused the Steam service's terms and conditions, Lombardi asserted that they would have removed the game if it had been offered by any other developer. A day after making this new policy, Valve subsequently removed four yet-released games from the service that appeared to also be created to purposely create outrage, including AIDS Simulator and ISIS Simulator. Within a month of clarifying its definition of trolling, Valve removed approximately 170 games from Steam. In addition to removing bad actors from the service, Valve has also taken steps to reduce the impact of "fake games" and their misuse on the service. In May 2017, Valve identified that there were several games on the service with trading card support, where the developer distributed game codes to thousands of bot-operated accounts that would run the game to earn trading cards that they could then sell for profit; these games would also create false positives that make these games appear more popular than they really were and would impact games suggested to legitimate players through their store algorithms, affecting Steam's Discovery algorithms. Subsequent to this patch, games must reach some type of confidence factor based on actual playtime before they can generate trading cards, with players credited for their time played towards receiving trading cards before this metric is met. Valve identified a similar situation in June 2018 with "fake games" that offered large numbers of game achievements with little gameplay aspects, which some users would use to artificially raise their global achievement statistics displayed on their profile. Valve plans to use the same approach and algorithms to identify these types of games, limiting these games to only one thousand total achievements and discounting these achievements towards a user's statistics. These algorithms have resulted in select false positives for legitimate games with unusual end-user usage patterns, such as Wandersong which was flagged in January 2019 for what the developer believed was related to a near
