Using services that "brush" QQ metrics (such as followers, likes, or views) violates Tencent's QQ Terms of Service and is an unethical practice. Engaging with such websites poses serious risks:

1. Account Security: These platforms often require you to log in with your QQ account, which may lead to password theft or account hijacking.
2. Account Penalty: Tencent actively detects and penalizes accounts involved in fake data manipulation—your QQ account could be suspended or permanently banned.
3. Malware/Scams: Many such websites carry malware or are scams that trick users into paying for non-existent services or stealing personal information.
   If you want to grow your QQ presence, focus on legitimate methods: create valuable content (e.g., interesting posts, useful shared resources), actively interact with friends or communities, and build genuine connections. This not only keeps your account safe but also ensures sustainable growth. Please avoid any illegal or unethical practices.
