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
