Taylor Swift threatens "trademark" lawsuit against Celeb Jihad

Singer Taylor Swift is threatening a trademark infringement lawsuit against a website “Celebrity jihad” for presenting (nude) pictures that it claims are of her but are not.  How is this a “trademark” issue?

The story broke on CNN Monday morning.  Here’s a story from International Business Times, link. 

“Celeb Jihad” has its own account here. Note: the site is very slow this morning.

My favoite song of Swift is "Mine", on YouTube here.  In January, it was the most common song on Sirius XM on a car business trip to Charlotte.
