UPDATE 3/5 Evening: The links are back up!
The Tweeters whose spam seemed to plug MSNBC shows Morning Joe and the Ed Show now have different links than earlier, when they were connected to a social media promotion company. This is the search for phrases which apparently promoted Morning Joe. These are searches connected to the Ed Show.
As you can see, these Tweeters now link to a dead page on a service called Host Gator.
And when you directly try to link http://followersdelivery.com, the promotion company in question, you reach a dead page on the same hosting service.
What the hell just happened?
UPDATE: 3/5 Apparently some people are getting through to the site - It seems to attempt to redirect them to a dead page with a different URL - and then after a pause it goes to Followers Delivery. In my case it goes to this URL: http://followersdelivery.com/cgi-sys/suspendedpage.cgi.
I don't pretend to be enough of a web expert (or any kind of web expert whatsoever). But that's what I'm hearing. I suspect it depends on what kind of system you have.
