some continued talking to me without responding to the fact that I was asking math questions.
Because it's weird and condescending, and the kind of thing people will just ignore. A bot would try to answer everything and fail. They'll try to solve the reimann hypothesis if you ask.
What these people - and they were almost certainly people - were doing is likely "blanking" you. They noticed an inappropriate social behaviour and ignored it in the hopes that you would get the hint that it was inappropriate without any need for a confrontation.
Frankly I don't have any patience for that. Have you ever asked that question and gotten a wrong answer? That would be a bot. If the answer is no, that's because you haven't found any bots. I answered to prove to you that you're a paranoid weirdo, and also because fuck you.
I'll also note that you ignored me telling you to stop talking to me. Does that make you a bot?
