Multiple identical postings

What can we do about people like “filby” who enter multiple identical postings? I counted around 5 of the following:

“H1B – (from India,elsewhere) Congress fooled by cheap U.S. companies”

Hey, dude, quit hitting the submit button so many times. You need to hit it only once.

I get highly irritated at these multiple identical postings, which are done either by someone who keeps hitting submit, or by someone who figures that multiple postings will get more attention than a single posting.

What it gets you is IGNORED!
