Months ago I started in the SEO world. I bought 100 private proxies from squidproxies and paid $160. I wanted to pay a high price to have exclusive IPs. At first, if you aren't specific, they'll give you Google-banned proxies. But no worries, they'll replace them the same day. Support and server speed are OK. You'll need to 'negotiate' with them server locations (i.e. "give me more US and less Estonian and Romanian proxies"). After weeks of usage, I started to see Google captchas and finally a total ban. I investigated and found out that some of my "private" proxies had been used by others (for the time they were mine). The bad thing is when they are aggressive spammers. stopforumspam ipcheck 220.127.116.11 I could even see some IPs declared as "toxic IP". Let's face it, users don't have any direct means of knowing whether their IPs are being shared. And that's a lucrative business for proxy companies. I send them a complaint, but they obviously denied the evidence, and offered me a refund, which I accepted. After briefly trying the world of free public proxies (and being unable to get one working), I discovered VPN services. I purchased a subscription of HideMyAss for $11.52/m. You install a program (it also proxifies traffic) and with a single click you have access to 59,000 IPs in 63 countries. The funny thing is that so far I've used hundreds, but haven't seen already a single captcha.
