I thought that one was fairly safe, because we mention it RIGHT THERE ON THE FRONT PAGE FOR FAE’S SAKE.

Cat captcha used to be on the wiki, worked OK for a while. Then microsoft decided it didn’t wanna run the cat captcha anymore.
KA101 is fond of cats and would be very inclined to use the Asirra cat captcha if it was still operational. Folks looking at adoptable kitties is a good thing, as it may lead to adoptions and less shelter crowding.
So the wiki was Jammed for a while, GlyphGryph and I removed the captcha code for about an hour or so to fix, and in that process we got oh, about a hundred spambots signing up for accounts. Some folks just went sleeper, most used their talk pages for SEO spam, and a few vandalized pages.
So I implemented question-based captchas there (after google’s reCaptcha didn’t care to actually cooperate) and called in the rest of the admins to help with the cleanup. I appreciate Kevin and Rivet pitching in with the Whack A Spammer, and now the wiki is becoming helpful once more.
Here on the forum, things were OK until the spam invasion. I wasn’t there to see most of it but got a phone call(!) one Sunday because the forum was seriously swamped. After half an hour trying and failing to find a way to tighten matters via the server (I have server access, but wasn’t a forum admin at the time) I changed the server settings to lock the whole forum down until Kevin could sort out the problem. He did, and that was the first level of question-captcha on the forum. There were about three there.
First thing I did after being made an admin was to tighten up the captcha questions here. There are now fourteen, and you have to get two right to register. I’ve just tweaked 'em a bit, though since you’ve passed, that’s unlikely to be of much help.
Math captchas are pretty easy for a machine to work, I should think, given how much math is involved in DDA. SMF doesn’t support multiple-guess captchas, but we supply possible answers for most of the questions now.
