Once we know it's actually you, we can first ban your account so the hacker won't be able to use it.
I don't have any signed messages, however I have alternative methods available:
I can give you IP locations, my broadband provider information, I can EVEN login to the Skype posted on a thread before any password changes were conducted, dating back from months ago. The ORIGINAL e-mail (never changed from 2014, until last week by the hacker) and the old password can be provided too upon request.
I'm mad right now, as this account took me ages to build and I've had it for ages.
And to Chris, Theymos takes ages to respond, but with the proof I have, all e-mails from PMs are on my original e-mail from 2014, I was hoping he'd help. The user hasn't been on the account since last week, so was hoping something could happen, I don't see how he's able to change my password/e-mail without Bitcoin talk sending me a notification to my e-mail though!
JUST FOUND SOMETHING!!!!
ON MY PRIMEDICE ACCOUNT I HAVE DEPOSITS DATING FROM 2014, and the BTC Address deposit matches a post on my thread from ages ago, surely if I can show evidence of that, I can have my account back?
