spambot capabilities.
Posted: Fri Jan 19, 2007 4:08 pm
Does anyone know the current capabilities of a modern day spambot?
I have googled a bit like this guy Neil Gunton's articles about how
he researched spambots and captcha.net. From what I have read,
spambots have an inability to detect distorted text in an image.
My question is how distorted does it have to be because I am developing
a image generator in PHP for use in an email form but I am designing it
for systems that do not have a freetype library installed and just use the
standard gd type library. See below at the image generated, and is this
distorted enough? PHP image filters do not seem to have a distortion
