Purchasing QQ profile likes (名片赞) through third-party "代刷" services carries significant risks and is not recommended:

1. Violation of platform rules: QQ’s user agreement explicitly prohibits artificial manipulation of engagement metrics (like likes, followers). This can lead to account penalties—such as temporary restrictions, permanent bans, or removal of the purchased likes.
2. Security threats: Most "代刷" services require you to provide your QQ account information (or even login credentials), which exposes your account to hacking, data leaks, or unauthorized use.
3. Scam risks: Low-priced offers (like 0.01 for 1000 likes) are often fraudulent—you may pay but receive no service, or get likes from fake/bot accounts that are quickly detected and removed by QQ.
   For genuine engagement, focus on creating interesting content, interacting with friends or communities, and building your profile organically. This is the only safe and sustainable way to grow your QQ presence.
   Please prioritize the security of your account and comply with platform guidelines. Avoid using such risky services.
