I can sign a message with a wallet address I posted earlier than 2017 on that account (and already have for the mods), yes "trickyriky" is my account, I am reluctant to post the other address in public as I don't want to give them chance to go editing, and screw my chances of getting it back.
I found it and already archived that page (that you posted the address in).
You can do it using what "Potato Chips" recommended or
https://archive.fo/It'll be safer to use an online screen capture tool such as this one:
http://archive.is (recommended)Now even if he edits that post, there's a proof (from your unedited archived post) plus if you check that thread, someone quoted your post on the next page (those valid evidences will stay there).
Im not sure I like the idea of getting my main account down voted, as if or when I get it back I would then have to get them removed.
It would take a day or two to remove those negative ratings (when you get the account back).
Take note: You have the chance to warn other users (by providing the sign message so DT1/2 members can tag your account), so they won't trust whoever is using your original account and eliminate the chances of him/her scamming someone using your account.
Ahh thank you, I assume it is now safe to post the signed message that I sent via pm?

thank you"
I can sign another, just as soon as core finishes catching up.

I still don't like the idea of having to deal with negative reports / trust on my main account though.
