ReCaptcha and FancyCaptcha bouncing back after correct answer!? Ie. they are broken.
For the record, 1.16.2 was the stable version of MediaWiki recommended on the website when I installed the ConfirmEdit extension.
Running ConfirmEdit on 1.16 since some early alpha in 2009 without problems. Maybe switch to simple math (at least to have a proper process). Also bot-looking accounts can be human too (that's what I experienced in the past months) so captchas like simple math are not working 100% well.
I stopped them by using $wgCaptchaQuestions using fairly simple insider questions that only my target group can answer. That stopped all spammers from registering and editing. --Subfader 18:49, 16 October 2011 (UTC)
I did say Simple Math does work (in the opening edit) but the two Captcha based options do not. I am familiar with administrating user generated websites. Simple Math isn't cutting it anyway, so I have to up the ante. Simple Math in a MediaWiki website could be conquered by the most rudimentary of scripts. I could code one myself in a half hour.
@Subfader: Please try one of the Captcha options if you can / see if they work for your 1.16 setup or not. Thanks.
Do the maintainers watch this page? I can't imagine there being a more important extension in the MediaWiki stable than this one.
@Bachsau: An upgrade on a lark is something I am not yet quite up to. Plus it seems like a backport would be in order.
