The Problem with Bots

So you know those spam bots that randomly add you on any messenger program and act like they are a long lost friend or saw you on the dating site you never joined?
I have this weird obsession of trying to get them to admit they are bots.

I know that doesn't make sense. I mean....its not like they are sentient. They are just preprogrammed with things to say. But I'll still just reply to everything they say with things like 'You are a bot", "you aren't fooling me", "just admit you are a bot" and then finally I try to break them by yelling "THIS SENTENCE IS FALSE".

I don't know what I'd do if a bot suddenly did start responding to me intelligently. Probably freak out.
