thanks for that but as you see i have never associated a BTC address to my account ...
---snip---
a quick search on your post history, I found these two posts with btc address in them
they're not explicitly posted as staked addresses, but it shows that you control those addresses
it's a long shot but maybe admins and mods may take it into consideration
can you sign message with any of them?

Yes I still keep all of my addresses and wallets intact- i believe. will come back from my vacation and will make sure i can sign a message from them, since currently i have only my secondary laptop with me. the question is how do i make an admin to approve it?
