Hello,

anyone has experiences with captcha vs recaptcha ( http://recaptcha.net/).

There is a plugin for dokuwiki (http://www.dokuwiki.org/plugin:recaptcha) -- my interest is how strong the system is to defend against bot spammers, rather than other good faith things (i.e., helping scanning books for free).

Cheers,
Daniel

Hello,

just to let you know that over the weekend the ACL (user authentication) for write access to wiki portals of the project has been turned on.

Anyone that wants to write to the wiki has to create herself/himself an account. The reason for requiring user authentication is weakness of the captha system used for anonymous posting -- during the past weeks lot of wiki pages were updated by spam bots.

If anyone is aware of a stronger captcha-like system to be used for anonymous posting, write back here. It has to work with dokuwiki.

Cheers,
Daniel
