I have gsa running with serengines and captcha breaker. im using it for tier 2 (pointing to some web 2.0s on tier 1), then tier 3 that uses verified urls from tier 2. tier 1 I just have comments, article sites, directories and web 2.0s (provided by serengines). so far, submissions are 1722 and verification has completed with only 13 urls verified. Is that normal? Can I speed it up and/or improve success rate?
