My brother is a photographer active on Flickr, and I know they have the right click deactivated to prevent people from stealing other's photos. Are they able to take the same measures here with writing?
No, but there are ways to catch those that steal: even though you have copyright on HB research on google cos. that can track things on the internet for you, another way might be too peruse mags. at your local barnes and noble etc.that cover what you write about. Best thing is to search engine say; how to protect written copyrights. If you sue could claim any profits and/or damages.
