It has records of phone numbers and most WG's use it to search for information on a punter. So when searching misscurvesemma phone number on true caller the name registered to the phone is Diane Smith. Also worth checking your own punting phone to make sure your name isn't on there.

Is it an app, for smartphones?
If so, I can't check it out, cos I still punt with a poxy basic nokia phone.
