So I'm in the market to buy relevant links with some higher PR to my well established website. It appears that most are selling links to some old dropped domain that they slapped a themed blog and feeds on. Look at this site as an example: aularius dot com It's a PR 5 site and the dude wants $100 for a blogroll for a year. And after seeing numerous sites/offers like this, I started wondering if maybe I should build some of these? What do you guys think? Is it worth the effort? Is there a service that pretty much auto-does all this? Thank you!
