Using services that brush QQ visitors (fake visitor counts) is not recommended, as it violates QQ's platform rules and may bring multiple risks:

1. Account security risks: Many such "cheap" websites are unregulated. They may require you to provide QQ account credentials or personal information, which could lead to account theft, privacy leaks, or unauthorized use of your account.
2. Platform penalties: QQ has strict anti-cheating mechanisms. If fake visitor behavior is detected, your account may face restrictions (e.g., limited functionality, temporary bans) or even permanent suspension.
3. Scam risks: Some services may take your payment but fail to deliver the promised visitors, or use hidden charges. There is no guarantee of service quality or after-sales support.
4. No real value: Fake visitors do not contribute to genuine interactions or meaningful connections. They only create false data, which is useless for building a real social presence.
   If you want to increase your QQ profile's visibility, it’s better to focus on legitimate methods: share interesting content (e.g., articles, photos, videos), actively engage with friends or groups, or participate in topics you care about to attract real, interested visitors. This way, you can build a healthy and sustainable social circle.
   Please abide by platform rules and protect your account security. Avoid using any non-compliant third-party services.
