Blocked or deleted? Easy 10pts?

[Ilove Internet]

He doesn't show up on my friends list, but he does in chat. I click our old chat conversation and his picture is gone and his name is "Facebook User" I can still send him messages, but all of them fail and have an error. His profile does not show up on search.

Earlier, I think he blocked me because his name and picture appeared in chat but I was not able to send him messages. His page showed up in search, but when I clicked it there was an error. Other people could access his page, but I couldn't. If he did block me, there would be no reason why I'm guessing.

This person does not show up any more so I can't see their page when I type thier name. Could an error have caused this? Please tell me if you think I was blocked or he was deleted.

So was I blocked then he deleted his page? Or deactivated temporarily?
Thanks! Will give 10 pts to best answer
