he can see it
Good, personally I don't have a problem with "mysterious newbies" having access to see my IP address, they probably need it "when handling the new account recoveries system". As for my own understanding, if my account locked from being "suspected to be compromised" do I only need to send them an email which I used on my account and "provide some evidence that I owned that email, that would unlock my account right?
Yes, I believe if you send them an e-mail from the e-mail that you used to create the account, that would be proof. You can also stake a bitcoin address on this thread
https://bitcointalk.org/index.php?topic=996318.0. Basically you sign a message with a bitcoin address that you control and in the future, you can sign another message using this same Bitcoin address. For privacy, use an address that you have not used and will not use for BTC payments.
