Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use". Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use.
There's actually an official World's Fair Use Day dedicated to celebrate that policy! Don't get me wrong, I respect your will to stay completely out of any ccopyright law breaking or association in it, but if the reason is only to protect this forum from getting closed down, you can relax and take a few steps back without a care in the world. Hurray for Fair Use!
That fair use policy is the reason why even huge, best known non-profit fan sites such as The Leaky Cauldron and MuggleNet are using graphics made out of movie stills from Harry Potter movies and photos of famous people - yet the copyright holders of the used pictures have not torn the sites down or asked them to pay anything.
Also, please take note that since the companies do not give a rat's butt about huge, best known fan sites using actual pictures, fan sites that by the way have been advertised with screenshots in a legally published, profit book - thus they certainly won't give rat's butt about some small, relatively unknown forum including avatars using copyrighted pictures or including links to non-profit sites using them.
That's why the Fair Use policy exists in the law; so that we wouldn't need to go this extreme in protecting our beloved sites.
I wish to ask if you could possibly consider allowing at least links to non-profit (fan) sites? Just the links, no one would be posting anything illegal to this actual forum.
If sites have been closed down it's been because they were profit without permission or didn't have appropriate credits and disclaimers on them. Allowing links to non-profit sites would not have this forum breaking any laws - the Fair Use policy makes it so.
What do you say? (:
