Member BitcoinBus contacted me through telegram about his account being hacked.
We were both judges at a
Credroom contest thus we have had our contacts @ telegram
He did not post his signature or address to be staked before

but I was able to to take a screenshot of his account
right after he contacted me. Rather impossible to have telegram hacked as well, so I think this might be legit issue.
