Preventing Forum Spam-bots?
A concerned reader asks: "Recently it seems that forums have become the new target for spam bots advertising everything from porn to casinos. The forums that I admin are constantly harassed by these bots even though you must enter the visual confirmation code code (the picture with letters/numbers) as well as reply to an e-mail in order to register. This only started a few months ago so I'm suspecting that some new spam program was released that somehow gets around these anti-bot measures. How can I get rid of these annoying bots?"
Just display a confirmation page with the goatse.cx picture.
Anyone who can still click on the confirm button is not human.
I have seen some captchas that ask users in plain text to solve a simple arithmetic or logic problem.
While not illegal, some may considering it amoral to discriminate against stupid people.
