Hello,
I installed the Web Wiz Captcha a few weeks ago. But in the last time there are coming empty requests again and again.
This is the code for the configuration of the colors and lines:
'Background Colour
strCanvasColour = "ffffff"
'Border Colour
strBorderColour = "B79A5C"
'Character Colour
strCharacterColour = "B79A5C"
'Random Character Line Placement
'This places the characters at different line levels on the canvas, this is good at preventing OCR software reading the image but still allows the image to be readable for humans
blnRandomLinePlacement = True
'Random Character Skewing
'Random Skewing is good at preventing OCR software recognising characters
blnSkewing = True
'Making one of the noise levels and line noise the same as the background colour and the other the same as the character colour
'is good at preventing OCR software recognised characters by using colour filters to remove noise
'Pixelation Noise #1
'This is the pixelation noise level, random pixels which prevent OCR software recognising characters
intNoiseLevel1 = 6
strNoiseColour1 = "ffffff"
'Pixelation Noise #2
intNoiseLevel2 = 6
strNoiseColour2 = "000000"
'Noise Lines #1
'Random lines overlaying image, prevents OCR software recognising characters, but can quickly make the image difficult for a human to read
intNoiseLines1 = 8
strNoiseLinesColour1 = "000000"
'Noise Lines #2
intNoiseLines2 = 8
strNoiseLinesColour2 = "ffffff"
Captcha looks like this:

Design is based on the design of the website. Colors should definately not be replaced.
I think the level of difficulty is strong enough, when I make it more difficult maybe the users can't read it anymore. Has somebody a solution for this problem?
Thank you very much,
kind regards
