The report is here: [escrow.com
This is a FWIW post. The report doesn't include brokers at Uniregistry, GoDaddy and any number of brokers who rely on other solutions- such as brokers whose clients rely on lawyers / contracts "for protection" vs. funds escrow.
Also, there are brokers who choose to not make their sales public.
I've done business with Andrew Rosener and I've enjoyed his professionalism. He's a no nonsense guy ~~ will discuss value ranges, won't initiate with low ball offers, etc.
At least one listed broker/service is hands down the worst I've had to contend with. AFAIC, a broker - a REAL broker / brokerage - has a duty to know domain values and know something about the registrant, a duty to advise clients regarding what a reasonable offer is, and a duty to NOT deliver offers that are nonsense / a waste of the registrant's time. I've simply stopped responding to inquiries or "offers" from certain brokers because they are unfiltered. YMMV.
