I'm sticking to my observations that most artificial link building schemes are of little value when it comes to ranking web pages in the search engine results.
Top keyphrase contenders in competitive environments usually have either deployed exceptional on-site optimization or have effective off-site influences. Most often though, it's some combination of both.
About Grey Hat SEO - Even the most powerfully deceptive off-site manipulation trick (link building strategy) isn't necessarily the only search engine optimisation that'll show up at the top of valuable search results. There's tons of examples of ethical SEO atop the puffed-up piles of linked nonsense.
