Fathom, you seem bent on believing that malicious competitors creating malicious links would have zero power to hurt someone else's site, but you sure haven't convinced me.
First things first...
1. demonstrate the website owner conclusively had absolutely nothing to do with what happened, then after that
2. demonstrate the links that conclusively caused this effect, and then
3. show the "competitor's" timeline of development that supports this occurred at the appropriate time.
You haven't proven any of these occurred... and you want me to convince you they didn't... I did that already.
I love experiments so I've got a website that is 100% clean... so how much money do I need to give you (or the best negative SEO) to prove I'm wrong?
