The reason that the comments were deleted is because some Flickr members were posting graphic and detailed online plans to extract revenge on the thieves. I hope they get tarred and feathered, or sued to the moon, but I can understand why Flickr can't allow people to use their site to organize a vigilante raid.
Higher ups at Flickr have apologized to Rebekka, and while she is obviously still riled up about this, she is staying on Flickr, just exercising more control over who can access her images. If you've followed Rebekka's rise in popularity in the online photo community you know that Flickr has brought Rebekka at least some fame and fortune. Definately more good than harm in my eyes.
I think that part of her problem stemmed from the fact that while her images were not full res, they were about three times larger than more typical web friendly size. Even so I'm still amazed that the criminals were able to enlarge them as big as they did, and sell them as fine art. Before we tar and feather them we need to learn their techniques!
The potential for images being stolen from Flickr is no greater than any other public photo posting website (such as TPF), other than Flickr is very popular. I have no doubt that unscrupulous art directors are cruising Flickr, and other websites, for free stock photography. I've had photos stolen off Flickr. It ****ed me off, and I quit Flickr for a while. Now I'm back. Like Rebekka, I've decided that the potential good influence on my photography to come out of the Flickr community is greater than the potential bad.
It comes down to freedom of information. How can you keep it locked up whether it's photos, writing, music, video, or whatever? The giants of the software, music, and movie industry spend billions of dollars every year to protect their copyrighted materials, yet how is that working for them? As far as I can tell people seem to think it's perfectly fine to steal copyrighted music, movies, and software. What chance do I have to protect my work, if the big corporations can't protect theirs with all of their resources? The choices are to lock it away and let nobody see, or take my chances in an unscrupulous world.
