Can anyone please point me to a discussion on what proxies are all about? I mean this in regards for backlinks for example. What are proxies needed for? What and why are private proxies better? How many private proxies would be required a month for backlinking? How many backlinks can you get out of a certain amount of private proxies? Basically an idiots guide to proxies is what I need. I've probably got half of my questions wrong in the first place. This is my level of knowledge on them. Any help would be awesome.
