I'd want to know if the OP ever had a Spotify account before, with the same email (m*@gmail.com). I suspect he has, and that Spotify account was previously linked to the FB account. Another strong possibility is that he has an existing Spotify account which was created using Facebook Connect. Creating an account with FB Connect would provide Spotify his email, and Spotify would likely have created a user record for that email (this is the recommended behavior from FB). If either is true, then I think this is what happened: - Spotify has an old user record in their database, associated with his Facebook account. He might not realize this, especially if his Spotify account was created via FB Connect. - When he created the new Spotify account, Spotify had a bug/feature which linked the new Spotify account with the old Spotify account. - Spotify then sent a "logged in via FB Connect" signal to Facebook, which caused his Facebook account to reactivate. This is normal behavior for Facebook - FB interprets any login gesture as a signal that you want to reactivate your account (be it a 3rd party login via FB connect, opening the FB app on your phone, or logging into the FB website) This seems plausible to me, and wouldn't indicate any malice. Whereas Spotify's engineers writing a screen scraper to login to Facebook and secretly install an app seems exceedingly unlikely.
