Captcha: blank + 15 = 21

I’ve started using a Captcha for the comments.  Over and above the spam protection I’ve been using, I’ve been deleting more than 10 spam posts per day.  This is just a nuisance, but it has become a nuisance that is grating.

I’m pretty sure this captcha is eminently defeatable.  You just need to examine the page for the details and do simple arithmetic.  I suppose this plugin is going on the theory that you don’t (usually) need to be the most secure; you just need to be more secure than the other guy.

If you can’t perform the requisite arithmetic, you’re not fit to comment (hint: that computer thing you’re using almost certainly has a calculator available).

      My plugins folder has this as “Captcha by BestWebSoft” … let me know if you can’t find it that way, and I’ll see if I can get more information.
