Found a vulnerable website, if anyone's interested.

(Remove all the spaces and parenthesis.)

If you're smart enough, which you don't even have to be, you can form a pretty useful google dork outta that, I'd provide one, but that'd ruin the fun.

Another thing to note is that you can change the numbers at the end to about any number. It'll say there are no comments, but you can still post one. Basically, if you're good with css, you can easily host music or some videos on it, go brag to some friends or something

Have fun!
