Re: I don't understand
I think we need people on the 'white' side doing stuff like this 'because they can'. If THEY can then who else is already doing so? If we know 'how' then we can work on prevention/cure.
There's a difference between demonstrating that something is broken and offering classes on how to exploit that - I am personally not impressed with someone attempting to portray the development of a better spam mechanism as "security" research. To me, that's just someone seeking payola.
