Seems like there are more and more fake stars on GitHub these days. For example, this one: https://github.com/Hammerock?tab=stars, this https://github.com/MacKeepUS?tab=stars and this https://github.com/Hirakok?tab=stars. These people seem to be engineers from tech giants, but they all starred risesoft-y9/Digital-Infrastructure, WuKongOpenSource and Heygem, which seems weird. I think there's a 90% chance these are fake stars from bots.
