Happened to me to but I hide the conversation... I think its a bot because I was asking them random questions like what's 9+10. I also asked them what happens if the chicken crosses the road and they kept responding with the same thing lol :P
I don't mind there mostly bots you could try I did it ones and made it crash thanks to my friend Mats that gave me the Skype
It's not a pedophile. It's actually a bot in attempt to try and trick horny teens into giving them their parents' credit card number(s). Just block it and report abuse. If you see anyone that you don't know trying to get your Skype, just decline the request and move on with your day. Trust me, bots have tried to add me COUNTLESS times.
