I agree. If you use an email address as a fraud signal, you need to seriously reevaluate your decisions. I've met a site that blocked my Gmail address as "spam" once, but another Gmail address works just fine. In my case it was just a nickname, but using an email as fraud signal also feeds into racism. People who don't have an average white American-looking name will suddenly be flagged for fraud.
