a copyright issue

I was nearly drowning from amazement when I came on a site that had so many copyrighted images from others on offer for download, that I just didn't know what I saw.
I thought about informing each and every artist. But it would have stirred the CGC and it would have spoiled quite some happy vacation days for people.

Like always it's good to lean back and have it sink in, and suddenly I realised she was/they were violating the rules of her provider and host, and so I mailed them about the abuse.
I have asked them to take action.

It's four days now, and nothing has happened yet.
Let's hope the proof I have given them, is enough, and the matter is under investigation.

It would be great if someone who speaks spanish or portuguese would help me, as this concerns a brasilian site.

I'm OK to inform those who are interested, but I don't want black lists or something like that.
I do however believe that the artists as a group can take steps to end this.
