My sites were victims of negative SEO. One was 13yrs old, another was 8yrs old. It was on page 1 for all its KWs. Our competitor bought thousands of links and sponsored wordpress themes and killed our top performing keywords. Google penalized us for those selected KWs only, which meant a loss of 80% of traffic. It's so pathetic. You can't explain it to the reinclusion request/web spam team because they're most likely all outsourced staff.
Anyone can do it and they only need to spend $200. They just goto fivr or blackha*world, spend $50 buying xrumer links. Goto DP forums, request for a few sponsored themes. Upload them to free wordpress sites. The site targetted will be nuked from Google within 6 months guaranteed. It works every, single time, unless the site is huge, e.g. Microsoft, Google, IBM, etc.
