It's beginning to look as though one of the moving-image captchas will still be needed to keep spammers at bay in 1.2. Both my 1.2 forums were new, so it took a while for the spammies to find them, but they have arrived. I reported & deleted two clear cases of registration spam. One of these would have had two hits in the StopForumSpam DB (which was configured) but it wasn't even moderated. Overall this does appear to be XF's best anti-spam effort yet, but it's still falling a bit short, and I can't afford to spend potentially several hours a day cleaning this stuff up, so it's back to the captchas that require the user to move an image to complete his post/comment/registration.
