Hey, What success rate of account creation on phpbb is possible using (together) xrumer and decaptcher with (for example) good proxies, randomised email address at a catch-all domain, etc. And how would this be maximised? (Sadly, I don't know any service similar to decaptcher but for text captchas, but that's one obvious way.) In terms of just creating accounts I guess the problems come from: 1) blacklists, ie. akismet style systems and known or open proxies/ips. 2) creating too many accounts -- again akismet style system recognising botlike behaviour from ip/dns/ip-group/email address patterns. 3) captcha (decaptcher style service should solve this). 4) text captcha: xrum has a big list but it's presumably tip of the iceberg. (someone really needs to start a decaptcher style service for this.) 5) MODS. I had a look at the PHPBB3 antispam mod section, and there are a few that would give trouble -- but combined downloads are really low (like 10k total) so this seems actually like a small problem. Specific plug-ins could get round most? 6) Custom: Custom antispam code is almost bulletproof, but again very small numbers so no big problem. I don't know how much 1 and 2 actually matter on say phpbb -- ie. if most people use something like this or if it's just "worst case". I guess I can't get my head around why success rate seems so low even with captchabot (although I would assume decaptcher style service would raise this over captchabot -- anyone have any experience actually?).
