A few years ago, when I was a kid, I had to find lyrics of a songtext on the internet for english classes. I found which said it had those lyrics but I had to register. So I did it but I didn't find the lyrics I was looking for. Later I got a mail, which said that since I made an account there and used their service I have to pay 80?. They really had written that you have to pay for their service but it was far down a the bottom of the page and the text was relatively small.
Further, they also wrote about some articles which say that I'm obliged to pay, lawer talk, things most kids at my age wouldn't really understand.
They also said that they've got my IP, so they know where I live and it's worse if I didn't write my real address (which I never write on the internet)or that I said I'm 18 even though that's not true.
I was quite scared at that time, I think I was 14 or 15 but I didn't pay, or tell my parents. I searched on google about that page and found out that it's aimed at underage people and tries to scare them and make them pay that way. So I simly ignored them until they stopped.
That wasn't the only page from them. Later I found out that my brother and 3 of my friends also had been victims of that scam at the same time as me, only on different pages.
