Please excuse my ignorance -- how fast is that? Also, there's quite a
difference between identifying an "A" symbol and porn, isn't it?
Anyway, I guess an important show-stopper here is, that image spam is
seriously low these days. That is, a message containing the payload of
an image. Sure, there is much more spam containing links to images --
but fetching them for investigation is potentially harmful, since that
stuff can be and is easily abused to verify live addresses.
Just some quick thoughts...
