> They have a long explanation about liability and such. Can you summarize the liability explanation? Is the sender a lawyer/law firm or someone just claiming to be the copyright holder? IANAL, ask them to provide how they arrived at $168.00 as economic value of the image. Similarly, you should estimate the economic value of the image to your blog/venture. Did you generate any income from the blog? Can you quantify the value contributed by image to your income? For example, if you were running advertisement on the page, could you quantify contribution of the page, that the image is on, to your total ad revenue? Do not pay right away! Keep asking for more information like their validity of their claims of copyright, who owns the copyright? Where the image was posted? More work the sender has to do, less likely they will continue to badger you. In all requests, give them a definite time-period like 30 days / two weeks to respond. I am very suspicious of such claims demanding monetary compensation unless such claims were preceded by take-down warnings and legal warnings from a lawyer/ law firm. My guess is the sender is a fraud and I am sure you are not the only one they are harassing. Such claims are like 'spam,' sender sends out thousands of them expecting some will pay. Do a Google search on the sender, sender email address, reverse-image search to find where else the image is posted. Contact some of them to see if they received similar demands. Edit: If you decide to communicate with sender, I will suggest asking only one question in each email and then wait for response. Once you get response, then take a few days and ask another question. It will be a while before you run out of all your questions. You also get to see how determined the sender is to collect from you.
