That girl is not beautiful and I'm guessing she's a little bit too batshit to get proper fucked in a regular fashion. The redditor in his natural habitat (the internet) does the only thing he knows how to do when he becomes interested in a "female" and pours his beta virgin heart out to her over whatever they use to talk that isn't Facebook (hivemind privacy faggotism) so now she wants some dick so bad she's going to pay his way to England and hope that once he gets there he'll look past the fact that she's put on thirty pounds, has bacne and something mental that doctors can't treat because it would take lithium and a horse tranquilizer.
Maybe not a scam. I've had stalkers. Some people are crazy. Some people are girls. And crazy girls still need dick.
