Buying or selling QQ likes violates QQ's official terms of service and is not a legitimate or safe practice. Here are the key reasons to avoid such services:

1. Account Risk: Platforms strictly crack down on fake engagement. Your QQ account may face penalties like restrictions (e.g., limited posting, blocked functions) or even permanent suspension.
2. Security Threat: Many "cheap like" services are scams. They might steal your QQ account credentials, personal information, or trick you into paying hidden fees without delivering the promised likes.
3. No Real Value: Fake likes do not represent genuine user interest. They won’t help you build meaningful connections or grow your influence—instead, they may harm your reputation if others detect the inauthenticity.
   If you want to increase your engagement on QQ, focus on creating valuable content (e.g., interesting posts, helpful sharing), interacting actively with friends or communities, and building real relationships. These methods are sustainable and compliant with platform rules.
   Please stay away from any illegal or unethical services to protect your account and personal safety.
