You own small a grocery store, and as an altruistic service to the community you provide a public bulletin board at the store entrance. Town residents can use this to share public messages and advertisements. Someone with no relation to you anonymously pins a poster with copyrighted images to the bulletin board at the entrance. You originally had no idea the images were not the property of the creator of the poster (how could you?), but as soon as you are made aware of the problem you remove the poster in a timely manner. Does it make perfect sense to you that I (owner of the images) can now successfully sue you (the owner of the store and provider of the bulletin board service) for copyright infringement, and have you pay damages to me as compensation for the time the poster was visible at the bulletin board? More importantly, do you think making the store owner vulnerable to litigation is 1. in line with how similar laws usually work? 2. a fair administration of justice? 3. a net benefit to the town and society at large?
