Using third-party services that offer extremely cheap QQ profile likes (名片赞) like the one you mentioned carries significant risks, and it's not recommended:

1. Violation of platform rules: QQ's Terms of Service explicitly prohibit using non-official tools or services to manipulate engagement (such as likes). Doing so may lead to account restrictions—like temporary bans, removal of fake likes, or even permanent suspension of your QQ account.
2. Scam and security risks: Many such cheap services provide fake likes from bot accounts (which won’t help with genuine interaction) or may trick you into sharing sensitive information (like your QQ password) leading to account theft. Some may also have hidden fees or subscribe you to unwanted paid services without consent.
   If you want more genuine profile likes, try legitimate ways: interact actively with friends, share interesting content on your QQ profile (like photos, thoughts, or updates), or join QQ groups with similar interests to build real connections—this way, the likes you get are from people who actually care about your content.
   Protecting your account security and complying with platform rules is always the priority. Avoid these risky services to keep your QQ account safe.
