To see if those links relate to number one ranking, I looked to see what Google said about their ranking.
Step 1 - Went to Goodle directory
http://www.google.com/dirhp
Step 2 - Click Shopping, then Recreation, then Drugs, then Head Shops.
Step 3 - See that the site in question (that gets the fancy non working extra links that result in "page cannot be displayed" IS ACTUALLY RANKED 5TH in Google Page Ranking order.
So, hmmm that means that if Google's page rank is #1 in the directory, your site could be beaten be 5th place competitor? hmmmmm. Is there possible some inside programming action going on there? Maybe friends in googly places help shoddy sites by artificially pushing their position? Maybe not, but sure looks fishy.
Anyway, I have a hard time buying that "they got the extra links because of their number one page rank" theory because of the fact they're actually listed 5th by Googles own directory-page rank.
I see extra links for cbs, nbc, abc, book, cars, downloads, halliburton, washington post,
The thing all these sites have in common is that they are deep and wide. Maybe only the biggest sites (from Google's bot perspective) deserve extra links?
