I've had very good luck with a simple math (or other) question, plus a "timer" that that checks how long it takes to fill out the form. The combo of the two work pretty good. The timer sets a hidden field to the current time, and on submit, checks against the current time again. There's no freaking way to fill out this particular form in less than 10 seconds - so if less time than that has passed, it's a bot. This alone catches 95%. Question works good too. I've got one client that uses: "Donald Duck is a "Cow", "Dog", "Duck", or "Cat"?? Over the last 4 years, not a single bot has EVER answered the question correctly. Of course, all your data HAS to be validated/verified before getting inserted into your database. You're doing that too, correct? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:358352 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
