Maybe they are all correct in a way. What if Google implemented a conversion tool on backlinks that looks to see how long the user stays on the site after they came from the link. If they stay long enough it carries value, if the user backs out right away it flips something like an irrelevant score flag.
You mean tools like Google AdSense, Analytics, etc. that people gleefully put on their site because it's free until it feeds Google data that can tell them your backlinks are worthless junk?
specifics which are absolutely needed to resolve anything
When you have this many sites all suffering from the same problem your specifics are meaningless except in the case of someone else doing the recovery homework.
Not to mention in the SEO world every site reviewed is a site stolen (copied, mimicked, etc.) by someone else as you've just exposed a viable business model to someone else looking for ideas. Kind of like trying to have a steak dinner in the middle of a lion's den, BAD IDEA.
