Eh, it isn't too much trouble. And the basic anti-spam stuff I put in (ignoring captcha) stops around 2000 post attempts a day, so a few getting through while not blocking a single good user is acceptable to me. Plus the guys getting through are real people in remote countries (Pakistan is the popular one recently) that actually work around the spam filters in place, so adding a "What is a warbird" question won't stop them as long as it is multiple choice. I had one user go through 20 pages of manual sign up stuff with checkboxes that are sometimes required checked, and sometimes not, so they are very determined for their pennies to post here.

Post subject:
so make it an open ended question that is very specific
"in 2 letters, what is a warbird?"
"in 4 letters, what is this a picture of?" (a terrier)
etc
