Buying or selling QQ profile likes (名片赞) violates QQ's platform terms of service and carries significant risks:

1. Account security issues: Such services often require you to provide account-related information (or use unauthorized third-party tools), which may lead to account theft or hijacking.
2. Platform penalties: QQ actively detects fake interactions. Your account could face restrictions like temporary suspension, feature limitations, or even permanent bans.
3. Scam risks: Many "lowest price" services are fraudulent—you might pay but get no likes, or receive low-quality fake likes that disappear quickly.
   Instead of pursuing fake engagement, you can gain genuine likes through legitimate ways:

• Keep your QQ profile updated with interesting, positive content (e.g., sharing life moments, hobbies).
• Actively interact with friends and contacts (like commenting on their posts, joining groups with similar interests).
• Maintain a friendly and authentic online persona—real connections will naturally bring more genuine likes.
  Protecting your account safety and building real social interactions is far more valuable than temporary, fake numbers. Please avoid using such non-compliant services.
