You are looking for public or private proxies? What do you mean by "stable"? If you think about public proxies it's much harder to find good public proxies today. If you use private proxies and you have problems with bans the first thing you should check are settings. Maybe you use proxies with to many connections, to low delays etc. You have gave us not enough information to help you effectively.
I'm looking only private dedicated proxies. I mean that my dedicated proxies often fall down in speed and very slow works with my software.
What software are you using for scraping? Don't go over 1 thread per proxy and put at least a 30 second delay or your proxies will get banned fast with google.
I am working with many different software for scraping... thanks for the advice, I'll look for proxies from other seller now.
