I have not checked the PR of my site in about 6 months. It is just a junk site...It has about 10K backlinks from scrapebox auto accept sites and it has about 1,000 blogs so far over the past 6 months from wp-robot. Back then i didnt know anything about anchor texts.. so yea most of the links are of no help. I decided to junk the site and start fresh with my new knowledge. I junked it last night and was checking my backlinks.... How in the heck did my page get PR4?? Now my question. Since it is PR4 should i go back and build on it? Or just forward it to my new site that is a way more optimal in terms of SEO.
