[citation][nom]erdinger[/nom]Like the first executed murderer stopped all others from murdering? Yeah right[/citation]
I guarantee you there would be a whole lot more murders if the penalty was a light as the penalty for spamming is. You get my point...

It seems like alot of their logic is based on the assumption that a banner, ad, "spam image" has a background that is fairly solid. Wonder how it would do on an image that has alot of different colors and gradients.

Not much, the spammers are going to change their images, then yahoo will have to update the code, and the war against spam will continue.

will it be like the program that was meant to filter pr0n images? And identified a portrait of G W Bush as pr0n? lol..

I'd say it would be about as successful as that.. Couldn't they just run an OCR scan on the image? Most spam images have text on them... Surely any decent OCR algorithm could read it? And then just apply the normal text spam filters as before.. Cheaper, simpler, existing technology... Why waste money on something that wont work properly?

pixel thresholding analysis is done by a person watching the image and answering yes or no to the question "is image a spam?"

The worst part is that with news stories like this the spammers get advanced notice to "yeah, thats why the email is/will be getting more bouncebacks or blocks!"

Eh...

So how long until they add this to yahoo messenger and it's chat rooms? Their was actually a time when chat rooms were somewhat popular before the rise of social networks like drop "the" facebook and such.
