Handling a possible SCAM call

What Happened

Today I got called by 647 number, with a Thomas Hill on the line, who had a Russian/European accent. He claimed that he works for blockchain.com and is involved in account recovery, which is why I'm supposed to believe that the domain recoveringblockchain.com is legitimate.
I previously had a coinbase account, and I thought that there could be a chance that this was still legitimate, so I proceeded with extreme caution. "Thomas" asked me if I can share my screen so he can "explain" to me what wallet I was going to recover, and show me how to recover it. I knew that screen sharing is not really a way for someone to access my information or gain control of my system, and I was not going to open my bank account while screen sharing, so I accepted and he emailed me a zoom link. I joined the meeting from a private browser window, and shared only the private browsing window.
Next, he sent a link to a transaction on blockchain.com. The wallet had a balance of around $50K USD, and I immediately thought that there's no way that this is legitimate. I figured that I would have to pay "account recovery fees" before the funds could be accessed, and the scammers would ghost me after receiving the payment.
Anyways, I insisted on them being straight forward and telling me the next steps. He told me that next they would transfer the funds to a crypto account I own (they have to verify this). I was of course very skeptical, and to be honest I was being very closed off, so he said he'd send me an email and I can verify that it's legitimate.
Well after receiving the email, from the @recoveringblockchain.com domain, I knew that this was definitely a scam. I looked up the blockchain.com support page, and it clearly said that they don't call you, and they only send emails from the blockchain.com apex domain - I knew then that I was being targeted by scammers.

Preventing any Future Damage

Now that I knew who I was up against was malicious, I wanted to introduce roadblocks for them, and at the very least I did the following.

• Register complaints with the authorities.
  • The domain registrar, which is where the domain name's ownership is managed.
    • Using whois recoveringblockchain.com command
    • Determined to be namesilo
    • Reported to [email protected]
  • Email provider, which sends and receives mail for the domain.
    • Using dig -tMX recoveringblockchain.com
    • Determined to be titan email
    • Reported to [email protected]
