- fad chasing

- making plans without executing them, using forks as upvote button

- when you make or fork a repo, it shows to ur followers, hence same people each time

and yeah, they do things to make number go up, consider it "metagaming" as opposed to like, bad stuff. Anyone is allowed to play github how they want!

as always, check their original code, la commits done by their accnt, ignoring anything silly (small, low effort commits) as punishing someone for being silly, is a bit silly, look at their PRs, look at their projects they have efforted on, etc, if there are none, then just treat it like they had no github.
