Interesting findings here my friends. Based on my observations, I'd say we have a new agency that has cropped up. According to their contact page they are based at the following address: 75 E Santa Clara St, San Jose, CA 95113 charles@pr-review.com Someone should stop by and see what they are up do....
My advice is to avoid Crowd PR based on reviews I have read. If you can't afford a top tier agency like Agency 2.0 then your best bet is to hire out for small freelancers who specialize in one specific task. Can get great results that way.
