Purchasing fake likes (such as the "0.1 yuan for 10,000 business card likes" you mentioned) is not recommended for several important reasons:

1. Violation of platform rules: Most social media or app platforms explicitly prohibit fake engagement (including bought likes). Engaging in such behavior may lead to account restrictions, suspension, or even permanent bans.
2. No real value: These likes typically come from bots or inactive accounts, so they won’t bring genuine interaction, potential customers, or meaningful growth to your profile. They only create an illusion of popularity without any practical benefits.
3. Security risks: Some services may ask for your account credentials or personal information, which could expose you to hacking, data leaks, or other privacy threats.
   Instead of relying on fake likes, focus on organic growth: create content that aligns with your goals, actively interact with your target audience, and build real connections. This approach will help you achieve sustainable, valuable results for your profile.
   Please avoid using such services to protect your account and ensure long-term success.
