>Gmail also allows "[e-mail]" and "scammer+2@gmail" to be the same account.

This is a well-documented feature that has many legitimate uses. If you're trying to stop fraud, clip any gmail addresses after the +. For example, I believe Facebook does this.

I do clip it. I have to do many other things too (spending time and money) to counteract scammers usage of google's services. Given google's ability to track people, they'd could do more against fraud, instead of letting scammers use their services freely (hence my comment of them enabling scammers).
