Today I got an email: "Message Body: I was looking at your website and I noticed that you have a copyrighted image that belongs to me. It's called *****. You do not have permission to use my image on your site. I am writing to you to request that you either remove the image immediately or provide a link to my site: http://www.hiswebsite directly below the image. Or you can purchase it for use on http://www.mywebsite site only for $50 (USD). Thank you for your immediate attention in this matter, L.W- Owner of http://www.hiswebsite/ " That is all but he is my competitor and I won't give him a backlink so easy! What would happen if I tell him to screw himself? can he really do something?
