欧易担保公群分类@OOYY— Telegram Channel

This channel functions as the central hub for 'Ouyi Guarantee' (欧易担保), a service broker for illegal transactions. It manages hundreds of 'public groups' (公群) dedicated to various criminal activities, including money laundering (run-fen/shuifei), counterfeit currency sales, gambling (Lotto, Texas Hold'em), carding, and fraud services. It acts as an escrow service, only guaranteeing transactions that have been reported within the official public channels, and explicitly warns users to avoid non-official groups.

Facilitates illegal and grey-market activities, serving as a directory for fraud, gambling, and money laundering services.
