Sentry mba proxies help

Hi guys. I'm stuck on sentry mba


Where I can get decent and reliable proxies from?

With out paying for them? I've used gather proxy but most of them become ban with in seconds of using them. My configuration are ok I've ran them without proxies and seem to be ok.

Any help would be a bonus.

I've seen sites that sell private proxies but I prefer not to buy them
