Gmail filtering messages question

[ddelboccio]

I need the collective minds of this forum to answer this questions please.

This is specifically for my personal Gmail account...

Is there a way to create a filter to grab or block incoming messages that do not have a subject line?

I seem to be getting an increasing amount of obvious spam messages that do not contain a subject line (blank), but I cannot figure out a way to create a filter to dump these directly into the spam folder.

Thanks!

This seems like such an obvious SPAM loophole.  Quite surprised at this point Gmail has nothing to address this.
