In Argentina it's against the law too. I have never seen anyone, ever, stop at a stop sign. At most people slow down a little more than usual. Not even cops stop at stop signs. But if you don't stop in your driver test, they can theoretically deny your license. So this is definitely a regional thing.
Fwiw, I visited a lot of South American countries, and Argentina is one of the most respectful of traffic laws. But yeah, stop signs are merely a suggestion at best. People slow down way more in a "dangerous crossing" sign, than a stop sign.
I think it would be auctioned and sold to the highest bidder.
