Using third-party platforms to "brush" Douyin (TikTok China) points, followers, likes, or other engagement metrics is a violation of Douyin's Community Guidelines and User Agreement. Such behaviors not only undermine the fairness of the platform's ecosystem but also carry significant risks:

1. Account Security Risks: Most of these "brushing" platforms require you to provide your Douyin account credentials or personal information, which may lead to account theft, privacy leaks, or unauthorized use of your account.
2. Account Penalties: Douyin has strict anti-cheating mechanisms. Once detected, your account may face penalties such as content demotion, temporary suspension, or permanent banning, which will completely ruin your long-term growth on the platform.
3. Scam Risks: Claims like "1 yuan for 1000 points" are often too good to be true. Many such platforms are scams—they may take your money but fail to deliver the promised services, or trick you into paying more fees under various pretexts.
   To grow your Douyin account healthily, it’s recommended to focus on creating high-quality, original content that resonates with your target audience, actively interacts with followers, and complies with the platform’s rules. This is the only sustainable way to gain real engagement and achieve long-term success. Please stay away from any "brushing" services to protect your account and interests.
