Using services that brush QQ visitors is against Tencent's terms of service for QQ. Such behavior may lead to account restrictions, including temporary or permanent bans, or limited functionality of your QQ account.
Moreover, many so-called "super low price" brushing websites are potential scams. They might steal your QQ account credentials, ask for payment but fail to deliver the promised service, or even implant malware into your device to compromise your privacy and security.
Instead of pursuing fake visitor numbers, it’s better to focus on building real connections. You can share interesting and valuable content, actively interact with friends or people in related groups, and participate in community activities—these are legitimate ways to attract real visitors and make your QQ space more meaningful.
Please prioritize the security of your account and personal information, and avoid using any non-compliant services.
