I remember that one. It's sad, but part of me thinks situations like that really do exist in poor countries where bitcointalk's potential for providing a living wage spreads like wildfire through word of mouth.
I'm sure they do, but that one was bullshit because they started the sentences with the same thing and just regurgitated the same post but reworded slightly, so they all just belonged to one person who got a bit ahead of himself. If there already isn't some sort of offices set up to farm bounties then I'm sure it's only a matter of time before they actually will be, but we're already seeing proof of it in a small scale at least with the picture you were sent of the group of people posting away. These things will naturally grow and expand like any business or industry especially when the money is too good and easy to earn. The merit system has made things a little bit more difficult for them as you now can't just create as many accounts as you want and rise them through the ranks merely over time, but they're still going to find ways around it like buying merit and trading it between themselves etc and we've already seen multiple cases of that as well. Punishing signature campaigns obviously needs to be the next step because trash posters just shouldn't be getting paid in the first place and that's the source of the issue here.
