You are likely not important enough to scam. The first people I can imagine this being shown to are VCs in pitch decks who are only going to see this on a powerpoint and not actually on github. Very unlikely the VC will check github itself to verify the number, and if they do, even less likely they'll verify that the stars are real.

You're the kind that checks everything. Even if you had something valuable, a scammer wouldn't waste their time with you then there are easier fish to bait.
