Nancy's Web If you don't know where you've been, how do you know where you are?

Gotcha is sort of a take off on "captcha." The idea was first mentioned on http://drupal.org/node/166921 as a possible way to trick spam bots who try to use the Drupal contact form. I don't particularly like the extra step humans are required to perform in these "verification" methods, and some just don't work.

The idea is simple: Basically you place a bogus input field on a contact form, and use CSS to not display it. On submission you check for a value. If there is a value entered, then that means a non-human has been blanketing form fields, and the form post can be ignored as spam. The spam bot will probably never know.

This add-on module allows Spam module administrators to examine and modify the tokens used by the Bayesian filters to determine the probability of content being spam.
