Forum Дубликат is a Russian-language online forum and marketplace organized around member discussions, seller listings, and paid promotional sections. Its content spans cryptocurrency news and trading education, banking topics, travel services, fuel cards, cigarettes, and general buying and selling. The site also advertises services and products involving vehicle and identity documents, personal data, payment cards, account access, hacking, and methods to evade verification. Some listings promote services related to financial transfers, SIM cards, and database sales. These claims appear in forum advertisements and posts and are not independently verified.

The platform includes public discussion areas, restricted sections, seller categories, and a classifieds area for one-off listings. It also describes a guarantor service for transactions, deposit procedures, VIP membership, and paid advertising and banner placement. Forum rules and guidance on avoiding scams are presented alongside crypto discussions and banking news. Because the site advertises potentially unlawful goods and services, its listings should not be treated as evidence of legitimacy, safety, or legal compliance.
