I talked to him before and before I let I said "Fuck you" cause it got on my nerves and it said "you shouldn't have done that..." And I am not joking when I say this but I literally didn't play my laptop for a week cause of it.
(see? you must just have fun! cleverbot is just an AI, a good one, you can really have a funny conversation! if it starts to talk about things you don't like, just say something idiot and off topic, sometimes it will react funny XD)
oh, and this conversation isn't a fake, i promise, it won't be fun if it wasen't true!
