Pay site using freely available and stolen work

[sci.livejournal.com]

Hi, I joined just to make this post really, as I've been advised this is the right place to put it.

Stumbled across this the other day though while googling for "bunny girls" sometime deep in the AM.

They're both obstensivly "free" sites, but they require a sexkey.com pass, which charges $39.95 every month after a 3 day trial.
So someone's potentially making lots of money off the following artists freely available and purchacable work. That pisses me off.

I don't know enough names to put them to all the images, but I'm sure folk here could ID a lot more of the artists being stolen from.

Unsuprisingly, both domains have their whois information hidden by http://privacyprotect.org/, so any complaints would need to be made through them.

I'm unsure wether artists should complain individually, or try en-mass to get the sites shut down. Thoughts? Possibly demanding the contact info from privacyprotect so the issue can be raised more directly?
