Buying or selling QQ business card likes (especially through such low-price, non-official channels) is not recommended, and here are the key reasons:

1. Violates platform rules: QQ's Terms of Service explicitly prohibit artificial manipulation of interaction data (like fake likes). Engaging in this behavior may lead to account restrictions (e.g., temporary bans, limited functions) or even permanent suspension.
2. High risk of scams: Many "low-price like" sellers are untrustworthy—they might take your money without delivering the promised likes, or trick you into providing account credentials (posing a threat to your account security, such as theft or unauthorized use).
3. No real value: Fake likes do not represent genuine social recognition or interaction. They cannot help you build real connections or improve your actual social experience on QQ.
   For a safe and meaningful QQ experience, it’s better to focus on creating valuable content and interacting with real friends or contacts. If you encounter account issues related to this, you can contact QQ official customer service for help.
