Still, my experience shows that when you have over a thousand of subscribers, your content is stolen by at least 5 splogs every day - and most of them only last for a week, after which every disappeared splog is replaced by a new one. And if I actually decided to do all the things to make those splogs take the content away, I'd need a dedicated employee only for such issues, I think - which I don't think is reasonable. And once you can make one splog remove your post, you will have a new one already. And you can worry about it as much as you want to - it will hardly change the situation
