An anonymous reader writes "A computer science student at University College London put together FitFinder as a bit of a joke — it's been described as a cross between Twitter and personal ads, and it rapidly became very popular. The university took exception to this and started by blocking the site from being accessed on campus. Not content with this, a few weeks later it fined the student £300 and had him take the site down completely. Currently, the site is still offline, although there is a petition with several thousand signatures requesting its return. In the meantime, a site called PhitFinder has appeared, claiming to have no link to the original."
