Using QQ brush-like services violates QQ's official terms of service and carries multiple risks, so it is not recommended to use such services:

1. Account security risks: Most brush-like websites require you to log in to your QQ account or provide personal information, which may lead to account theft, password leakage, or even being used for illegal activities.
2. Platform penalty risks: Tencent strictly cracks down on non-compliant brush-like behaviors. Once detected, your account may face penalties such as restriction of functions, temporary suspension, or permanent ban.
3. Financial fraud risks: Many brush-like websites are scams—they may charge fees but fail to deliver the promised likes, or trick you into recharging more money with false promises (e.g., "recharge 100 get 500 likes"), resulting in unnecessary financial losses.
   If you want to increase the exposure and interaction of your QQ content, it is recommended to focus on creating valuable, interesting content and actively interacting with friends or fans. This is not only compliant but also helps build genuine connections. Please protect your account security and avoid using any non-official or non-compliant services.
