2016, giving users more control over what games they want to see or ignore within the Steam Store, alongside tools for developers and publishers to better customize and present their game within these new users preferences. By February 2017, Valve reported that with the second Discovery update, the number of games shown to users via the store's front page increased by 42%, with more conversions into sales from that viewership. In 2016, more games are meeting a rough metric of success defined by Valve as selling more than $200,000 in revenues in its first 90 days of release. Valve added a "Curator Connect" program in December 2017. Curators can set up descriptors for the type of games they are interested in, preferred languages, and other tags along with social media profiles, while developers can find and reach out to specific curators from this information, and, after review, provide them directly with access to their game. This step, which eliminates the use of a Steam redemption key, is aimed to reduce the reselling of keys, as well as dissuade users that may be trying to game the curator system to obtain free game keys. Valve has attempted to deal with "fake games", those that are built around reused assets and little other innovation, designed to misuse Steam's features for the benefit only to the developer or select few users. To help assist finding and removing these games from the service, the company added Steam Explorers atop its existing Steam Curator program, according to various YouTube personalities that have spoken out about such games in the past and with Valve directly, including Jim Sterling and TotalBiscuit. Any Steam user is able to sign up to be an Explorer, and are asked to look at under-performing games on the service as to either vouch that the game is truly original and simply lost among other releases, or if it is an example of a "fake game", at which point Valve can take action to remove the game. In July 2019, the Steam Labs feature was introduced as a means of Valve to showcase experimental discovery features they have considered for including into Steam, but seek public feedback to see if it is something that users want before fully integrating that into the storefront. For example, an initial experiment released at launch was the Interactive Recommender, which uses artificial intelligence algorithms pulling data from
