You can't just ask people to do that for you, especially when they don't know that person. Sorry, you just have to apologize yourself.
Or just take a break/distance until that person has got time to talk to you again.

I agree with you on that.

I see.

I just asked him about my art trade's not coming two years ago so I got mad or crazy. So I try to tell him I'm really sorry but he block me. It made me. I just be patient and wait.

I didn't know he blocked you. Is there another way you can get in contact with him again? Discord, Skype or something?

I don't have any contacts.

Dang. :(

Could you please tell him I really sorry?

I'd be careful here. Technically I think it's in the new rules that it could be considered harassment if you try and get a third party to contact someone that's blocked you.

I see that someone already contacted him on your behalf but I'm not sure if furrytailgal can see your journal that they linked to if he blocked you. (I have been blocked once here and you can't respond to someone's post and maybe not even see their profile, but I only know the blocked side. I'm not sure how it would work for the one doing the block if they could see your stuff.

I see.

Could you tell him I'm really sorry?

davidc090193 already posted something on his page saying you wanted to talk to him.

And who is davidc090193?

Could you please tell him I really sorry?

I don't know that person. :( It's not gonna change anything and it would probably be a bad idea if I suddenly get involved.

I see.

Yeah, who is davidc090193?
