I got a weird message on skype?

I just re-downloaded Skype today for my iPhone, and minutes after I signed in I got a contact request from a user named maggie.blake583, someone I don't know. I asked who they were but I didn't get any reply. Has something like this ever happened to anyone else? (the user has no profile picture or any information)

Yeah, that happens to me sometimes. I ask who they are and hours later, they give me a generic response, and it's obvious that they are a bot. I would just delete them.

Yes, that happens all the time on the net. The rule of thumb in situations like this is to just not respond to the person if you don't know them because you have no idea who they could be.
