Maybe this is what you're looking for. The reason I would not "attempt" to bring a competitor down with negative SEO is because I am an ethical person. Is that better?
Negative SEO is about ranking bad publicity to harm your reputation.
With so much knowledge on your part though it feels like you must be typing from within the Googleplex...
I'm unbiased to a fault. I prove/disprove popular thinking... I don't just accept it.
