I'm sure there are automated programs, but I know for a fact, from a person
who used to work in a place like that in New Delhi ... they have those sweatshops
all over the place. And they are not treated very well. She had worked there in
2009 (so 3 years ago). I can't imagine much has changed. But that's what she did.
She was paid to register and post on a pre-defined list of blogs and forums. Also,
was instructed to make comments on lists of video sites, flickr, and whatever
social sites where popular in 2009. I should have her write an eBook about the
experience ... it's very interesting.
