I will send a new request to easyDNS, it seems to me that they were quite responsible last time.
Found out about exch.best sometime back and informed exch support, but didn't want to take action against them without the domain getting added to the list. Also, I believe Tucows ultimately took down exch.cash as xorpian pointed out(Not easyDNS).
Domains registered with Namecheap are difficult to get suspended, so feel free to call them, send to their headquarters a physical letter, or to mention/tag them on social networks. Any action can help.
Already tried other ways of putting pressure on Namecheap earlier, but they keep protecting those scam sites.
