Many of the stargazers of my MLtraq GitHub repository https://github.com/elehcimd/mltraq look weird.
There is no verifiable information, seemingly from China; they have a massive count of stars/forks. My attempts to contact a few of them failed, so I tend to think these are bots.
There are site where you can buy stars on GitHub. [1] By starring more than just customer repositories, these sites reduce the risk their customers are caught and reprimanded.
Stars are often used as quick indicator of project popularity, maturity and trustworthiness.
