Using third-party websites claiming to "brush" QQ SVIP permanently is not only a violation of Tencent's Terms of Service but also carries significant risks:

1. Account Security Threats: Most such sites require you to enter your QQ account and password, which may lead to account theft, unauthorized access, or even loss of your account.
2. Fraud and Scams: Some sites may trick you into paying fees, providing personal information (e.g., bank details), or completing fake tasks, only to deliver no actual service.
3. Malware and Viruses: These sites often contain malicious links or downloads that can infect your device with viruses, ransomware, or spyware, compromising your data security.
4. Account Suspension: Tencent actively detects and penalizes accounts using unauthorized methods to obtain premium services. Your QQ account may be temporarily or permanently banned.
   QQ SVIP is an official paid service, and the only safe way to get it is through Tencent's official channels (e.g., the QQ app, Tencent's official website, or authorized platforms). Please avoid using any third-party "brushing" services to protect your account and personal information.
   If you want to enjoy SVIP benefits, consider purchasing it through official channels—this ensures your account safety and access to legitimate service guarantees.
