Granted that none of the plethora of threatened furry lawsuits has ever (or likely will ever) actually go to court, this doesn't really effect anything. It does mean, however, that sites like ours can not only continue to mock idiots, but actually counter-sue under certain circumstances:
Copyright holders must assess whether material has been used fairly before they demand that it be taken off the internet, a US court has ruled.
...
Rights holders who demand that material be taken offline without such an assessment risk paying out damages and costs to whoever published the material, the court said.
So sayeth
this here article over at The Register. The case in question involves a video posted to Youtube that just happened to have part of a copyrighted song in the background. Universal sued under the DMCA, and lost - the judge ruled that the video was covered under the Fair Use Act. The defendant counter-sued, also under the DMCA, which places the burden of proof of infringement on the copyright holders. In other words, it states that they must prove infringement as opposed to the defendant proving fair use, and if they don't, they are liable for any damages the defendant has incurred.
What does that mean for us here at Viv and other sites where "copyrighted" material is mocked and sometimes photoshopped to hell? Well, first off, the material must have an actual copyright on it. More importantly, if one of you knuckleheads posts a piece of artwork protected by Fair Use, and some twat from FA complains to our web host and gets us shut down, then we could potentially take them to court for it. (Not that I ever would because our web host rocks and also because that'd be pretty fucking gay/idiotic/furry/etc - but the point remains.)
Of course, my ass is also covered by some other bit of law that says I'm not responsible for anything you people post here, but that's beside the point.
Betting is now open for how long it takes some idiot furry to counter-threaten another idiot furry under this ruling due to claims of art theft.
