Competition. It's a funny thing.

Competition is a funny thing. When placed in it, you immediately find ways to defeat your opponent in whatever clever ways possible. If they're winning, you automatically think (for some) that they cheated or that the system is broken. If you're winning, you automatically think (for some) that it's because you've mastered the game. Even if you see some kind of loophole or exploit in the system that allows you to win, and you admit to it, there's still a sense of pride in knowing that you've found and utilized such a thing to win.

That being said, I have no idea who this girl is, but she's going to steal my Dukedom away from me on Yelp.

The question is: why do you care?

The answer is: I don't know. Why should I care that this woman, who is probably nice, has more check-ins at a public transportation stop than me? I know that once I leave the area that I'll no longer be able to check-in and thus will lose the Dukedom anyway. Who knows? I don't and that's probably why I think competition is so funny. It really makes us do such funny things.

Whatever the case, she's probably cheating.
