"Like any online community that cares to combat spammers, we code our user-submitted links so that Google ignores them for the purposes of calculating page rank (specifically, we attach “rel=nofollow” to anchor tags). Somebody trying to gin up their Page Rank by encouraging complaints on Get Satisfaction would be sorely disappointed."

Uhm.. their links ARE dofollow. Do a quick CTRL+U and then search for "home" and "contact". They both clearly say "Hey, Google, come check me out. The water's fine."

EDIT: I see that their reviews are nofollowed, but most of the linkjuice has already been passed by the site in these sidebar links. Additional boost isn't supplied by negative reviews, no, but it is in businesses best interest to submit here so that they can get that linkjuice push.
