Yes, he has one bitcoin wallet number for 2017. Although this message has been deleted and is archived in the forum, I think that for many of the doubters here, signing from this wallet would be good proof of account ownership.
However, you can predict that the story of the loss of this wallet and all the other excuses will begin.
Speaking from personal experience, I wouldn't see this type of excuse as a bullshit as I don't have access to several old bitcoin addresses (it was on purpose btw, I just got rid of them). I know its not the smartest thing, but some people don't care much about these things.
Holy crap!
Now the real drama is started, hahah
A few days ago some people claimed why I do not use my old wallet, why posting behavior changed bla bla,, lol
I told them gimme a minute I'm not at home, but they tagged me.
Fortunately, I imported some old addresses on coinbase which saved me.

I'm just being social butterfly with a lot, otherwise, I wouldn't have signed the message.

sickk haha this is not a very surprising thing.
I have used over 100 wallets, most of which have been deleted.
If he comes to do business with me I will tell him to sign the message otherwise it is irrelevant to ask someone to sign the message.
I can use neutral feedback or a personal diary if I think someone's activity is suspicious.
