I got tricked into going to a kiddie site. What is going to happen?

I was playing a game online and while we were waiting this guy pasted this link and said it was a funny video and to watch it so I went to it. (so stupid of me) and this warning came up but i just clicked accept or something and then this thing came up that said we have your information and your address and someone will be going to your house soon. I'm 17 and that's extremely disgusting I would never purposely look at that. Is someone really going to come to my house? Or is that a joke? it seemed pretty real tho...
