ok gonna contact the email as soon as i figure out this msg siging thing, can anyone help me with figuring out msg/address signing :
I found this website for MEW (myetherwallet) : https://medium.com/@eugen_lechner/sign-and-verify-a-wallet-address-with-myetherwallet-1a46f6e2853e
but I am still having a hard time figuring out how to use this format .

-----BEGIN BITCOIN SIGNED MESSAGE-----
My account <account> has been hacked/lost. Please reset the email to <email>. The current date is <date>.
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----

Here is the unedited post where I posted that address: ...

p.s I read on the forums that these account recovery application takes days to get a reply and your msg might get ignored if u are not using the format and information.

This Btc Address 1Bmn4sUjCETqF8UJdUs9EFkapAhV5CDy7k is from Bitrex exchange . I have access to the account .
This Btc Address 17Nbse9QxPhXJJVoS9rLDzDbCZJ3m6NUGs is from Poloneix exchange . I have access to this account too .
This Eth Address 0x09D55b75DBcFf2D5E4D43d5F6A6eD2Ee483F0fA5 is from myetherwallet(MEW) . Have access to this address too , and I think MEW allows signing msgs so I think Can sign the msg using this.

I havent send any email yet because I would like to have most of the necessary information before emailing them so as this can be quick and doesn't take much of their time or effort.

My account got hacked some time ago.
I received an email from bitcointalk that email is changed if this isn't you click the link to lock the account.
So luckily I locked the account.

Now I would like to recover my account.
I saw this link Regarding how to recover accounts :
https://bitcointalk.org/index.php?topic=5089777.0
And I have a number of issues with which I need help regarding this post :

First I am a complete noob and haven't used the signed address feature even once but looked up some posts and still not so clear about that.

2nd: are second what is a signature in the following context

-----BEGIN BITCOIN SIGNED MESSAGE-----
My account <account> has been hacked/lost. Please reset the email to <email>. The current date is <date>.
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----

Here is the unedited post where I posted that address: ...

3rd: This is a link to my old profile  https://bitcointalk.org/index.php?action=profile;u=316656
The address I used here DVK9njqKkZNuBvXKfLYTGkgiAEQVnX6CbT is not a bitcoin address but a deeponion altcoin address, I just found the wallet.dat file on my pc and started the local wallet so now I can sign a message using it but I don't know if it will be accepted.
The only bitcoin addresses I have used on bitcointalk were from Poloniex and that too I did on pms and so since I dont have access to pm since account hacked and I don't think I can sign msgs using poloniex address so I don't think they will be useful at all.

My account remained offline for more than a year now as previously I didn't think I had the deeponion wallet and have no other proof to verify my account to get it back but now since I found and rebooted my old deeponion wallet I have hope that I have enough to get my account back.

any help will be appreciated .

English isn't my primary language so Sry if my post is hard to understand.
