Incredibill this happens only if you are first to start with or have something very unique, Copying the idea doesn't work, why there is no another twitter or facebook?
I was out there early, not big but #1 in my space, been scraped and even my AdSense code copied. DMCA's, C&D's and lawyers about the only thing standing between me, my livelihood, and being buried alive by lowlife scum.
re: Twitter & Facebook, it's a bigger thing to copy, takes real money, resources and serious IT, and until recently hadn't proven to be cash worthy except bilking VC money.
Groupon, on the other hand, was an instant cash cow and everyone is out to tackle them.
