I'm not sure about proxies. Currently I scrape proxies for free using proxy multiply. It gives me 40 proxies everytime I search. I've currently encountered problems with GSA and google where my current scraped proxies shows as banned ip's in GSA. (although it says theyre google friendly when I test them using proxy multiply or GSA). I'm thinking about buying proxies proxies. 10$ proxies gets me 10 proxies a month. I'm thinking that 10 proxies will get exhausted and banned too early because most of the proxies gets banned easily. Please enlighten me.
