Someone wrote in complaining that their comment was lost because of a wrong answer to the anti-apam-quiz.
Said commenter presumed it was a cultural reference they weren't getting. Actually the answer can always be found in the post. The idea is that a commenter responding to a post they haven't been reading carefully enough actually is spamming.
That's the theory, but said commenter spent serious time here, and then was engaged enough to complain through the contact form. So maybe it's really easy for new visitors to miss one little detail in the post. Also, there are apparently no second chances; pushing the back button on a failed entry brings you back to an empty comment form. I see how that would be annoying. I can't easily change the no-second-chances thing, but I could change the quiz or use other anti-spam-measures entirely.
Is this an isolated case or do other people have problems with my anti-spam-quiz?
Have you ever lost a comment?
Would you prefer I used captchas or math problems?
If there was no human-proof at all, but innocent comments occasionally spent a day in the spam-queue before I rescued them, would that be better or worse?
Have you ever been unable to comment because you just didn't get the question? Or has the right answer ever not worked?
Would you comment more if there was no quiz?
If you already comment, would you put less thought in it if there was no quiz?
Do you have other points on comments, moderation, and spam control you might want to share?
For obvious reasons, there is no anti-spam-quiz on this post. Update: Sorry, after 13 deleted spam comments, I decided to bring the quiz back even on this post. Also sorry to the guy who actually did write a comment and will have to wait another day for an answer because I wrote this instead.
