At first glance, my first assumption is that he is a Filipino because I strongly believe that his name was derived from Pres. Rodrigo Duterte (our current president) but I am not sure of it because there are tendencies that it was just a coincidence. So I visit his post history to find more clues and yeah I found out that he is a Filipino for real — no doubt. Read this post

In my point of view, he was a troublesome member. The way he post seems so rude for me. I don't even know what's wrong with him. Nevertheless, on behalf of the Filipino community, I want to say sorry. This is so embarassing for all of us because my fellow countrymen became the only one who distrust satoshi. What a shame!

No, we can't really tell if this account was on the hand of a Filipino member, the post you are referring to was just a sarcastic post, more likely he is just portraying he was the President the way he addressed replies. You don't have to feel sorry it hasn't been concluded yet, yep, it was really a curious case distrusting the creator, he's the rare type.

Don't worry the user isn't that eccentric as it was and he love YouTube. Ahhhh, how amiable.
