What was this skype bot's intention

Got a Skype request from some random girl (probably a guy irl) and out of complete curiosity I added her. The conversation went like this:

Their replies make 0 sense if you don't reply how you you're expected to reply when you see a hot girl add u so it's obviously a bot. What I want to know is what are they trying to get out of tricking people like this?
