X-Cart5 have social login function. It can facebook account or Google+ account. User login and create account this e-mail address.
Case of Google+, e-mail address is gmail. But antiFraud decision "free mail" and up to fraud level. This contradicts it.
In my opinion, gmail, iCloud account don't warning account. It's popular mail account.
