Best service for building Private Blog Network?
 

I got a tip from an SEO guy to create a private blog network (PBN) with links pointing to my webiste. And I have some questions.

1. Which service is the best for setting up a network of blogs/websites? (easy blog networks, GoPBN etc)
2. Where is the best place to get abandoned or expired domains?
3. And does PBNs even work?

I think you should build your own PBN network rather depending on others. I use Godaddy auctions to pick good quality of expired domains.
