So I sold a few names the other day and the buyer insisted to use DN.com. I've never used them as I always used the industry standard Escrow.com. Anyway, after my transaction and after I had verified my identity submitting a scan pic of my license AND a pic of me holding my license they still have doubts about the authenticity of the transaction. So they requested me to send them ALL receipts for domains that I purchased months before that were included in the transaction. That was a little weird but I obliged. Now they say they will process and issue my payment. Should I be worried?
