I dated a girl for a while who I stayed friendly with after we split up. She posted an online dating profile (circa 2003?) with just enough information about herself to be Google-able. Some guy Google'd her, found her on her university website (she was doing a PhD), and emailed her telling her she should be a bit more careful, and, PS, did she want to go on a date?
She replied calling him a creep, and reported him to the dating site.
