Why does XEvil need proxies?

XEvil is one of the fastest captcha solvers there is. It recognises more than 8,000 types of captcha and can decode over 100 ReCaptcha images per second. But like any automated solver it has a ceiling: the harder ReCaptchas don't fall every single time, so it retries — and retries from a single IP are exactly what Google watches for.

The two problems proxies solve

1. Blacklisting

When your XRumer or GSA SER run posts and searches quickly, sites and search engines notice. Google starts showing a ReCaptcha on nearly every action — and if all that traffic comes from one IP, that IP gets throttled or blocked. Proxies make each request look like it's coming from someone else, so there's no single IP to punish.

2. Retries and lost links

Every ReCaptcha XEvil has to retry is time lost, and often a backlink you never built. Fresh IPs from a rotating pool reduce how often Google challenges you in the first place, so XEvil clears more captchas on the first attempt and your link run actually completes.

Why private proxies, not free ones

Google is good at spotting recycled, public proxy IPs — many are already flagged before you use them. Free proxy lists are slow, unreliable and frequently blacklisted, which defeats the point. Private IPv6 proxies built for XEvil give you clean addresses and a pool large enough to keep rotating.

Do you still need proxies for posting?

Yes — separately. The IPv6 proxies here are for XEvil's ReCaptcha solving. The posting your link tool does needs IPv4 proxies, because most forums and sites are IPv4-only. The two jobs use two different proxy types.
