Copying an entire site is a bit different, if you copy one of their articles I doubt anything would happen. Maybe a sternly worded email.

If you copied their entire site, used their name, and removed their ads I'm sure they'd get lawyers involved.

Oh, but you could have something in the footer that says "full credit for content to daisy mayall", which is on par with their citations.

It's a fun idea though - seo bomb them until their bottom line aches.

I don't think (not a lawyer) that they could do anything if you put a disclaimer that it is a parody of their "creative work."

That should allow use of slightly changed (LessAdsDailyMail) trademarks, and proper citations could handle the rest.
