Buying or selling QQ profile likes (such as the "1 yuan for 10,000 likes" service you mentioned) violates Tencent QQ's User Agreement and Community Guidelines. Such behaviors not only disrupt the platform's fair and authentic interaction environment but also carry significant risks:

1. Account Security Risks: Most of these services require you to provide account information (like QQ number and password) or use third-party plug-ins/software. This may lead to account theft, privacy leaks, or malicious attacks.
2. Account Penalty Risks: Tencent actively cracks down on artificial brush-up behaviors. Your account may face penalties such as temporary suspension, restriction of functions, or even permanent ban.
3. Scam Risks: Many such services are fraudulent—you may pay but not receive the promised likes, or the likes obtained are quickly cleared by the platform (since they are from fake accounts or bots). Genuine profile likes come from meaningful interactions with friends and valuable content sharing. It is recommended to focus on building real social connections on QQ rather than pursuing false data through irregular means. If you have other questions about using QQ properly, feel free to ask.
