What I do is have people solve a simple math problem (ie. 3 + 4 = ?) where they would enter 7 in a text box. The first two numbers are random single digit numbers so that answer will change each time. This is easy to implement and seems to work well.

Then I read it is better to have the person uncheck a checkbox before submitting. Ted From: Fogelson, Steve [mailto:[email protected]] Sent: Tuesday, April 20, 2010 3:20 PM To: [email protected] Subject: Witango-Talk: Spammers I had a little misfortune this last weekend. I have a "Recommend It" program on our commerce sites where someone can recommend the site to their friends by entering up to 3 email address and a personal comment and then the program emails accordingly. You guessed it, I believe someone wrote a crone program to use this to send out spam. Started on Saturday afternoon and ended when I caught it Monday morning. Ironically the ip address originates down under in Australia. They must be familiar with the "taf" extension down there. LOL What are you guys doing to prevent this. CAPTCHA? Or some other strategy? If it is CAPTCHA, could you recommend where I could obtain a bunch CAPTCHA images so I can create this step to hopefully keep spammers from using the program.?
