I used their broker service to buy a really expensive domain via a client (squatter).

They ranted about how it's done totally anonymous and had to do all the communication.

They transferred the domain to us revealing the seller's WHOIS information (email, phone, name, address).

Ended up being someone literally walking distance from me in Washington, DC. So that's some crazy sketch dangerous behavior... I couldn't imagine what would happen if they sold to a really pissed off client. People are crazy over their company and personal names. Like hello incoming pissed off dude who just forked over multiple $xx,xxx to a squatter and now has their address.

Then I couldn't replace the WHOIS information because you needed the seller to confirm via their WHOIS email (GoDaddy support could not understand this / or I suck at explaining).

I almost just called the seller up, but instead finally found out GoDaddy allows you to bypass the WHOIS process with the email of your GoDaddy account.

Disaster. Don't really buy domains anymore but probably Cloudflare or bust at this point.
