Using third-party platforms to "brush" QQ-related services (such as likes, followers, space visits, etc.) violates Tencent's QQ User Agreement and related service regulations. Engaging in such behavior may lead to account restrictions (e.g., function limitations, temporary bans) or even permanent account closure.
Additionally, most of these so-called "lowest price" brushing platforms are unregulated and risky: they may steal your personal information (including QQ account passwords, payment details), defraud you of money (e.g., charging fees but not delivering services, or inducing repeated payments), or implant malware in your device.
Genuine account growth relies on creating valuable content and building real interactions with others. Fake data not only harms the fairness of the platform ecosystem but also fails to bring any substantive benefits to your account. It is recommended to use QQ services in compliance with the rules and focus on legitimate ways to develop your account.
