one thing i do know a little about is
seo...
things i can convey to you....
#1 yes the se's do "see" these links.
#2 regardless of #1 these links are near worthless because when you have so many links at one url their value is diminished accordingly. for example, i always laugh when i see webmasters trying to trade links on condition that "only sites with a certain
pr" need apply.
an extreme example:
the truth is it is way better to have an inbound link from a page with pr1 if it is the only link on that page than a link from a pr6 with a ton of other outbound links on it.
that all being said, (specifically) google is imho doing something very weird lately... ask me if you want more on that topic.
#3 relevance counts. inbound links from pages with similar content is worth more. spiders are getting smarter every day.
#4 se's do a whole lot less penalizing than many people think. think about this one... why would an se penalyze you just because it's spider found a link that anyone could have placed? don't worry about that.
