Well looking at Mechanical Turk [1] it seems that Twitter manipulation comes in at about 5 cents a 'hit' so if a Webby was worth $25,000 to you, you could buy half a million votes. I was wondering if you could go 'back in time' but couldn't find that, to see if there was anything like this in it.
That being said, there are lots and lots of bots on Twitter [2]and given how easy it is to program one, and the fact that folks might pay for it, wouldn't you like to have a 'twitter army' in your pocket that for the right price could give you a shout out? Heck people do it with zombie PCs all the time.
