So I remember visiting this website, they allow you to make a fake website URL. When your friend clicks the URL they are put into the site.
Now the trick is when the person click's the link it displays the bad websites they view. So you can find out what kind of research your friend likes.
Probably best not to post the website on these forums. Just send it to me on steam or something. It's a completely harmless website though, no viruses, no gore, nothing.
