I started off with 10 shared (3 users) proxies from a company recommended by an SENuke SEO service. They worked nicely in Scrapebox, but they were $1 each. So I thought I would scale up, buy more, and look at BHW for suppliers. I carefully read through all the threads to find suppliers that were OK with Scrapebox use. I bought 50 shared proxies first. The moment I started using these proxies they start to fail in ScrapeBox. It was so bad that I had to test the proxies every time before I scraped with them. The usable proxies went from 50 to 30 in an hour or so. They took about a day to recover, then back to the same problem different proxies failing every time I scrape, check backlinks or page rank. My home IP got banned for 24 hours because I initially wasn't checking every scrape and some of the proxies failed to remain anonymous. I analyzed my mistake as buying crappy shared proxies. So I bought some dedicated private proxies from another BHW supplier. When I run these 20 through the Scrapebox checker, 4 or so are bad, slow or 404 errors etc. This is before I have even used them once. Moreover, if I check again, it is a different 4 that are bad. I don't see how these are usable. I plan to ask for a refund rather than try to use them. My expectation was that private proxies would be good if I took care of them. I set all my ratios in Scrapebox to 5:1, so 20 proxies, 4 connections. Any suggestions for maybe something I am doing wrong or a good reliable, inexpensive proxy supplier?
