It is a meat-like substance which is delivered in a tin can. It can be quite
good for breakfast with eggs if you can stand the grease content.
I don't think it looks like meat. It's sort of a pink, semi-homogenous,
gelatinatious mass. I think Hormell (tm) uses SPAM as an acronym
for Sorta Pink And Mutilated but I digress

I don't really think you're message was spam. I was making a point.
I really don't see what the big deal is in all this.
I think you are right that EVENTUALLY people will realize that spam
is bad for business. In the meantime, if people can find technical
solution, that's great. If they can't I certainly don't want to
get the lawyers involved. SPAM is bad, but some cures are worse
than the disease,
