Hi,
I have installed the captcha plugin available for Dokuwiki and there are less attempts of registration since but I still receive here and there a mail stating that "the mail I sent didn't reach the destination" which is a fake mail adress.
I have read a part of what is here:
https://forum.dokuwiki.org/thread/9613
and I have seen you talk about Mediawiki having the same problems. However, the keycaptcha I would like to have for Dokuwiki is available for MediaWiki, as per the list I provided above, and also for SMF forum where I use it, and also for Wordpress where I also started using it.
I don't know if that's flash based, I have not noticed in fact. Anyhow it would be nice to have it for DokuWiki, because I can say with the results at the SMF
http://linuxvillage.net forum that it does a real good job! Since it was installed several months ago, not one bot has yet gone through.
Thanks to the ones knowing how to make plugins, to consider my request. :)
Regards,
Mélodie
