I sent the phone recording and emails to coinbase, and they acknowledged them saying "This report is super robust and gives us a lot to look into. We are investigating this scammer now."
I stand by my statement that the title is clickbait, as it's misleading on two fronts:
- It's the email, not the call recording that proves what Coinbase knew, but "recordings prove" sounds more sensational
- The email proves that Coinbase was aware of a sophisticated attack against a single user. You didn't have enough information to prove that there was a large scale leak of Coinbase customer data. There are sophisticated attacks against individual Coinbase users all the time due to the value of the accounts there.
Edit: Nevermind; I see you addressed that here:
