What is this?!

Hey, I looked up my name on Google (hey, I was bored!) and I found my poem on someone else's website! They didn't plagarize, they wrote that it was written by me but I don't get why the hell they have MY poem! I would be flattered but, I don't really understand why they had to post it on their site...or what this site is about. Check out to see if your poems are on it too:

And if you find out what this site is all about, please tell me! :)
