In reality, you would have to invest a tremendous amount of time, energy, and perhaps even money (to pursue legal action) if you set out to stop everyone who is streaming your content.
If youre developing a blog with information or news on a product or service in hopes of converting adsense clicks or cpa offers, your fresh new unique content is going to be harvested and there isn't a whole hell of alot you can do about it. Go out, steal someone elses stuff and call it even.
Now, if you're publishing a blog of your original music, love poetry, art, ice sculptures, short stories, or other intellectual property that may be near and dear to your heart... then yes, it may be worth the energy to try and stop someone else from calling it their own.
