Yeah I have read that post.
Problem is my PC has been changed / reformatted many times over throughout my time on this forum, and I don't keep large amounts of coins on a gaming machine (which is also the machine I interact with this forum with), and I have always emptied my addresses out and created new ones. I'm pretty sure I won't have the private keys to addresses I used in PMs (which would have been my personal wallet clients, not exchange accounts).
My only hope is finding a wallet address in my post history / PMs that is linked with some exchange account or something... The oldest BTC exchange (that is still online today) that I could find is VirWox, and I have access to this, but can't find any associated BTC address discussed here, only my PMs with the admin of VirWox back in the day.
Surely, seeing an account suddenly stop posting in English and change straight to Russian is a pretty big clue that it was hacked? This combined with the fact I have access to all the accounts talked about on this forum? It's really obvious the account changed hands in Oct 2017, and shouldn't be hard to see some new IP login and change the email somehow or whatever.
I want to be sure I have as much info as I can before PMing, but I'm almost certain I can't provide a private key to an old address...
