Bad math alert... (10000 * 100) / 1000000 = 10    ;)
Still the same answer though, was just mixing what I wrote with what I was thinking :)
Bleh, what's wrong with me today... it's 1% not 10%. Still within reason for a spammer. *smacks head to clear the fog*
So, that means that you need to allow maximum of 10 attempts per few minutes, so that there will be 0,1% change ;) Using Ted's technique I've found the perfect CAPTCHA -- and it's fun too: http://shorl.com/nomojeryprafri Cheers, Rob.
Hmm, LOL Ok, found him ;) He's under the ground ... :P Tijnema
