I've had a PR4 site for 4 years and it naturally picked up about 70 backlinks. In the past 2 months I did the following: 1. Paid someone to get 500 profile backlinks from PR3-PR8 forums (verified all links) 2. Successfully submitted 500+ articles with AMR, 2 links per article (verified all links) 3. Scrapebox Commented on 8,000 blogs - linking to the previous 500+ articles (to get the articles indexed by google). (all verified) 4. Used ContentNotifier to get 10,000 backlinks from directories. 5. Paid someone to get 6,000 backlinks using Xrummer (all verified) ... yahoo explorer still says i have only those original 70 backlinks! Seriously, wtf? Where are my backlinks? Any ideas?
