My answer is: they MAY do so. The absense of "From" is an 
"indirect" sign of anonymous spam. I.e., this message was 
generated not by a standard MUA but by some robot. And (as I 
understand) the main idea of current anti-spam fight is: "E-mail 
if for humans (also elves, dwarves, etc), but not for robots".

And nobody is _obliged_ to receive any e-mail. This is 
his/her/its free choice.

So, their software may be not broken but intentionally 
configured. Yes, they risk to loose valuable new information :-)
