Engaging in services like "QQ brush likes" (buying likes for a fee) violates QQ's User Agreement and Community Guidelines. Such behaviors not only disrupt the platform's fair environment but also carry significant risks:

1. Account Security Risks: Many illegal brush-like services require you to provide account information or use unauthorized third-party tools, which may lead to account theft, password leakage, or malicious attacks.
2. Account Penalties: QQ's anti-cheating system can detect abnormal like data. Violators may face penalties such as account restrictions (e.g., inability to send messages, post updates), temporary bans, or even permanent account closure.
3. Scam Risks: Most low-cost brush-like services are scams—you may pay money but receive no actual likes, or the likes may disappear quickly (as they are generated by bots or fake accounts).
   To gain genuine likes and attention on QQ, it’s recommended to focus on creating valuable content, actively interacting with friends or audiences, and building real connections. This is not only compliant with platform rules but also helps you establish a trustworthy and sustainable presence. Please avoid using any illegal or non-compliant services to protect your account safety.
