Do spammers fear OCR?
Nick FitzGerald recently sent me two sample spams that seem to indicate
that
some spammers fear that using images in place of words isn't enough.
They've
started to obscure their messages to prevent optical character
recognition.
I'm afraid they'll start using OCR themselves. One common trick to allow a
web
site to have an email address humanly readable but not harvestable is to put
it
in an image. That may not be so safe any more :-( Of course, they'd have
to
scan an awful lot of images in the hopes of finding an email address in any
of them, so they may not find it worth the effort.
