amusing yes, but i'm not certain its a good move.
every photo they post is a photographer that would claim copyright infringement.
if (psudo)photographers photos were widely circulated around the internet it might be hard to fight, but because these seem singular specific unique instances, it might be easy for the (psudo)photographers to claim a suit against.
If anything, each and every posted photo can be a subjected point for taking down the website (if someone hosts your legal work on their site, you can appeal for them to take down the content -- if 48 hours passes, the host of the domain usually takes the site down until the owner of the domain contacts them.
I think the site is playing with fire.
Just found it interesting.
saw this on a friends facebook post today.
(funny, sad, legal recourse, etc)
