So based on what it is written in the white paper of the xbricks project is that they want to "tightened" the identity or the identification,
so mean to say that there's already a solution to the problem in terms of scamming because if this will be tightened therefore the scammers will be lessen
It is possible that scamming will be lessened since scammers might get discouraged and decide to not join cryptocurrency exchanges that involve KYC before accepting a user but it doesn't mean that it would be impossible. I think for now the project can only guarantee fast and secure trading but it cannot guarantee scammers not joining the system since KYC doesn't actually involve submitting criminal records.
