Folks: this has always been the law.
What has changed? Why now?
A recent case was brought against a site hosting member content (that's what we do, too).
The judgement decided that because the site had moderation, the site could not claim that only the infringing member was liable. Moderation now can mean 'approval'. This is regardless of how heavy or light the moderation is.
We function better with moderators. So, we are stepping up our attention to copyright infringement.
I still think we would rather live in a world where so much information is accessible, and learn as a global society to respect the concept of ownership.
So, think reasonably, and don't mount your protests here, please. This thread is for questions - not debate.
@void - you are correct. Links are completely acceptable. Quoting from a published piece is still acceptable.
