Exotically coiffured businessman and self-appointed Republican visionary Donald Trump is the owner of the latest high-profile Twitter account to be hacked. Trump joins the esteemed ranks of Burger King and Jeep, with both companies suffering compromised accounts in the last few days.

The Trump hack was less colorful and briefer than the Burger King takeover. A single tweet was sent quoting a song lyric from Lil Wayne's verse in the will.i.am ditty "Scream & Shout." Trump appeared to declare, "These hoes think they classy, well that's the class I'm skippen."

In response to the hacking of Burger King and Jeep's Twitter accounts this week, Twitter put up a new blog post encouraging people to protect their passwords.

Here are Twitter's tips:

Burger King saw a surprising upside after its Twitter account was compromised on Monday: tens of thousands of people began following its account.

In a move that will excite McRib lovers the world over, the official Burger King Twitter account announced this morning that the company had been sold to McDonald's as a result of persistent drug-use by Burger King employees.

 Less than a week after Twitter unveiled Vine, the video-sharing app apparently has developed a porn problem.

As first pointed out last night by The New York Times' Nick Bilton, searches for #porn, #sex, and other associated tags brings up a handful of videos featuring male exhibitionism and other activity.
