I will create a link pyramid consisting of 300 high PR profiles with anchor text on the first layer and then 5700 profiles w/ verified links built to high PR as a second layer.
Huge SEO juice building.
1st layer of pyramid - 300 (I will over deliver on this) high PR
2nd layer of pyramid - 5700 profiles w/ verified
Perfect for those of you paranoid of getting sandboxed while still wanting the SEO benefit.
