As I mentioned in my earlier post, hosting providers can takedown scam domains sometimes. IP Volume is the hosting provider of exch.cash and they replied to me saying that the reseller has been informed to take immediate action.
Used ICANN domain lookup and found out that easyDNS technologies inc is the reseller. Sent an abuse report to them too. Let's see what happens.
If you can drop some of the additional emails, we can mass report these sites for urgent attention. Our job is to take those sites down and we can achieve that if we work together and not in isolation.
