Suddenly @cantlogin doesn't want to sign a message, but said this only a week ago:
I can prove it to someone that I trust without any problem at all. (only with someone I trust)
Signed messages can prove this to anyone, so either do it, or stop boasting about it.
Sure I can sign a message for you no problem. I trust you 100% and can do it when I get back my other account, or now if you add me to Telegram.
The borrower wants to repay their debt - let them then collect as soon as you sign a message.
Simple.
