Just confirming that the new measures are working. Spam is coming in and is flagged before becoming visible on the site, so that the moderators can either approve the post, if it's a false positive, or delete it along with any other posts by the same user and ban the spammer before their posts are even seen by APUG users.
I made a few tweaks so will probably revert back to the way it was. It seems to block 1 out of 20 legit people from registering and I then have to set them up manually, but if it's letting a lot of spammers through then it's not worth the new setting. Thanks for the heads up
