AW have tightened down things and don't allow so many fake accounts that they used to.
The scammers will still find a loophole though if they're determined. Nothing stopping a scammer registering an account with genuine ID and photos, and then once registered, change the photos for fake ones. The ID is hidden, so no one other than AW and the account holder can see it.
It's then down to us punters to flush out the fakes.
