Funny enough, I didn’t even notice since the first name was the same and they responded as if they were the OP, so I simply assumed they were. Considering the first account has the display name “Devamitta Bhikku” and username “Devamitta”, and the second account “Devamitta” and “Deva”, and they replied to my original question with the source of the code which I was unable to find myself by googling, I think we can safety conclude they are the same person, or they are deliberately impersonating them.
You might want to post that over in the #site-feedback thread, where I’ve moved a revised version of that part of my post here, where it is more on-topic.
