Interesting comments. I can see both sides of the story.

In the end I ended up reporting the site.

1) There was no way to contact the webmaster.
2) They used an image to indicate that users should "Please click the ads!" where there was no reason not to have used plain text. Seemed like a deceptive way to hide the text from a bot scan or something?
3) They were hot linking images from other sites.
4) Site contained hidden text trying to claim some legal nonsense about not being responsible.
