As Chris says, once on the internet you in effect lose control, so if it bothers someone then the only answer is for them to stop using the internet. I know my views on copyright are controversial, but I am just being practical. Also if someone wants to use one of my photos it does not bother me. In fact they are doing me a favour as I want to get to as many people as possible and it doesn't cost me anything or more importantly any more of my time.
