Yup when a lawyer doesn't understand the law you gotta worry. What it basically means is that posting up other peoples work on the web is illegal without the permission from the copyright holder. If pinterest themselves (as opposed to other forum members) are saying that they don't like people posting up their own content (for self promotion) then they could well be in some hot water. Otherwise, yes its you the poster who is responsible for the actions of your posting.... at least that is so long as this ACTA stuff is not implemented which makes all web site owners (and possibly the ISP in some drafts) liable for the users posts. So long as the website removes copyright infringing material within a reasonable period after being notified then they are ok. This is why YouTube stuff is taken off line all the time. They do not necessarily check who is the owner of material when a report is made. Hence this week a guy walking in the woods with birdsong was taken offline from some troll who claimed copyright on the birdsong. Now if the site is posting links to the material then it ought to be alright... except when it isnt. A reference to something illegal is now being treated as illegal by the USA. This is why the pirate bay are changing links to torrent files over to another format. The links to torrent seeds are not in themselves breaking the law but they are being treated as illegal anyway by implication of being an accessory. The US are pushing ACTA globally and the UK, France and most of EU are signed up but some of the member states have woken up a little and now there has been some resistance to it. The issue of course is that with this google and most websites like this one are now illegal. ACTA breaks the whole internet and its the usual arbitrary policing of it as to whether you stay online or not or have your domain seized ala Megaupload etc.

So if you think thats bad. Its just one of a million complete screw ups in the area of copyright law. Were rapidly approaching a copyright law meltdown. Clercon has it nailed !
