I stumbled on this a few days ago and have been mulling it over.
Basically I noticed that my partners iphone kept asking for a password to his old email address. Having had trust issues before between us I went to this old email address and signed in with his usual password. In there was a number of emails from a dating thing called Badoo. Most of them were stuff like "Kelly wants to get to know you!" or "4 new hot members in your area!". So giving the benefit of the doubt I assumed it was just general spam ... went further back into the account and an email saying "welcome to badoo!" with some log in details.
I logged into the app and found that his username is a combination of his middle name and his age. He never uses his middle name. NEVER. So when he told me that these details must have been pulled from something else he was using I couldn't help but smell a bit of bullshit.
No photo on there and no other details - no messages send and none opened so I can say he has been actively using it but HE must have signed up to it, right?
Or does Baddoo have form for creating false accounts using info it pulls from elsewhere?
