Screenshots don't prove anything. If you want to prove ownership of an email address from an old PM, you could report the PM to Global Mod hilariousandco (after all, his alt started this topic) to verify the address shows in that PM.
Ok, I have reported a PM from 2012 to Global Moderator Hilariousandco which contains my email address quoted. I hope he will confirm it and respond soon.
However, it's not uncommon for email addresses to change hands together with a Bitcointalkaccount, either when the email gets hacked, or when the account gets sold, so it doesn't really prove anything.
Yes, but it is uncommon for a VIP account, I take the security more seriously, also you need to consider a exception.
