I've been using Storm Proxies for 2 months for whois scraping. They were EXCELLENT for the 1st month, but in the beginning of July the error rates started climbing. By error, I mean not just the 'proxy error' message, but a 'short' response from whois, which is what they do when you're semi-banned. It doesn't contain expire date so it's useless to me.
The error rate went to 82% for a week, up until today it's dropping and the error rate was 75%.
And yes, I wrote to support and was just told to watch Loopline videos, which I had already seen and had nothing but setup info -- nothing about Storm Proxy errors. They've provided no useful response or info, so obviously we need to post here to help each other.
