Anyone has a suggestion for a simple (simplistic?) CAPTCHA mechanism?

Don't insert anything in this field: [ ]
It helps to make the internal names of the input fields random
with some (slow) time variation. Should work well enough unless
you're designing Yahoo's account creation page. Don't raise the
barrier higher than you need to -- diversity helps here.
All things considered, I will go with that simple approach, instead of
a CAPTCHA proper. In other words, a combination of randomized
identifiers and honeypot fields.
Here is a more extensive description of that technic:
