So proxies are the only thing that keeps me from doing own massive back linking BH way. These and captchas will raise monthly costs up quickly so I have decided simply to use service so I don't need to hassle with proxies. I find it hard to find good suite of proxies that really work in many cases like PHP web programming thru proxies (google and other website scraping), internet browsing as well as SEO software. And I know I will need more than ten proxies anyway, maybe up to 50. And they slow down everything. In addition I need to make them work on several machines: MAC, LINUX and WIN cause I have apps running on all of them. How do you actually manage to get proxies to work in various, keep costs down and things speedy? I want to know your secret!
