On the cs.rin.ru forum, Rule 5.3 mandates that users take responsibility for external links, requiring a clear description for all third-party content to prevent spam and prohibited material. Adhering to this rule ensures links are not flagged as "blind" promotion, while also requiring that posted links do not lead to offensive or prohibited content. For a detailed breakdown, see the Steam Community forum rules guide Guide :: RULES OF THE FORUM\ПРАВИЛА ФОРУМА

Rule 5.3 of the CS.RIN.RU forum dictates that users bear full responsibility for external links they post, with a strict prohibition against linking to content violating forum standards, such as pornography or violence.

• Complex DRM (Denuvo): As DRM becomes harder to crack (specifically Denuvo), enforcing Rule 5.3 becomes technically difficult. If a game cannot be cracked, it cannot be uploaded. This leads to a content gap where the forum may have threads for Denuvo games that remain empty for years, while other sites might host uncracked "wait for crack" releases. The rule enforces a strict "don't ask, don't tell, don't upload" policy on these uncrackable titles.
• Online Games / MMOs: Rule 5.3 essentially bans the sharing of most modern online-only games. Since these games rely on server-side verification (which cannot be "cracked" in the traditional client-side sense), the original files are useless. Consequently, the forum focuses almost exclusively on single-player or LAN-capable titles.

The forum's full name— The Steam Underground —is relevant here. The community focuses heavily on Steam games, achievements, and integration.
