When everyone has a voice you find out how few people have anything to say. And apparently some have nothing to say except, tacitly, I want money and I know how to get it without doing any honest work.
Well, it's possible they were entirely automated, I've seen some papers taking a script and generating an animation from it. I don't think anything like that is available off the shelf though and it would be way more trouble/money to write a program to do it than to hire a few Full Sail animation graduates to make half-hour animations that fit some word salad as fast as they can.
Xtranormal basically animated scripts algorithmically. I'll bet you could write an algorithm that would take certain inputs and create certain animations. I'll bet it would be a lot easier to staff a sweatshop full of entry-level computer operators who don't speak a word of english.
