Is Hugh Macleod's Twitter account hacked?

...or atleast that what it looks like.

As I am writing this post, Me along with some 14000 other people are being bombarded with back to back messages from Hugh Macleod, more popularly known as Gaping Void.

The spamming started at approx 3.20 PM IST and ceases to stop. All the tweets start off with a "Hi! My name is Hugh MacLeod, I make a living selling ads on my blog"

Here's a screenshot of the page

 

While majority of tweets focus on him living off the ads on his blog, there are the occasional tweets addressing a different topic

In the past there were instances of Britney, Obama and few other high profile tweeters whose accounts were hacked, so is this yet another case?
