I use... you gotta use caution, when you think is a fake, it prob is... you can ask girls if they facetime verify, if they dont, it usually means its fake/scam... some photos might be fake, I can tell you that, but there is a girl behing trying to hide their identity, so ask for verification... besides, you can read reviews if you reviewed one of them, so that helps to find the real ones!
stay safe!
