So I have been blasted with Neg. SEO links for the past year and after a partial Penguin hit I'm done just patiently disavowing and trying to be a nice guy. What is the most cost effective way of blasting 4 to 7 Competitors with 10k-100k spammy links / month for the next year? I hear Fiverr, Scrapebox, SEnuke, GSA. What is the most cost effective way to retaliate... or rather carpet bomb all of your competition. Also I dont give a flying duck about karma, retaliaton or whatever... ...only if everyone uses it, Google will finally start to ignore it.
