CS.RIN.RU, also known as the Steam Underground Community, is one of the largest and longest-running forums dedicated to game preservation, reverse engineering, and modding. Its content ranges from game cracks and emulators to "Clean Steam Files" and modding tools. Because of its nature, the forum is known for strict moderation and a large set of rules.

The forum hosts thousands of games. If every new user asked where to find a download for a popular game, the forums would be overwhelmed. The "lurk more" rule ensures that users have searched the dedicated topic, read the last few pages of replies, and checked the first post for links before posting a request.

Most clean steam files and cracks are neatly categorized in the main gaming sections.

On CS.RIN.RU, you cannot simply click a button to view the rules page. The forum software requires you to pass a "human verification" test. For years, that verification test has been a single, infuriating question:
