He used to be unable to tell usernames apart, I kid you not. He would ask me about what someone else said, and when I asked what was he talking about, he would copypaste their comment and said that I said it. But it was from a different username. And he was very insistent on it, he kept repeating, demanding an answer. And this happened quite a bit for a few years, so it wasn't like an occasional accident or something.
And it was for completely different individuals too with different styles, like me, and Octavia, and Kylie Fan. Kylie didn't even like me, and for quite legitimate reasons, as I gave the guy a pretty hard time for a couple of years.
So pretty obvious that his translator simply couldn't translate usernames which of course tend to be convoluted reconstructions of different words. MemesDLux4U and Squiggly_poo might not exactly translate easily. So he's not even using the Latin alphabet, since he coudn't at least recognize that the lettering looks different between users..
It seems now he's managed to overcome that technical difficulty, as he's no longer confusing different accounts.
