Screwing with a stop sign because you don't like it is a great way to end up on the wrong end of a huge civil liability lawsuit
They never fixed any of them. I don't think the DPW cares. These intersection just turned back into the 2-way stops they had been for decades prior.
Compliance probably technically went up since you no longer have the bulk of the traffic rolling it.
Getting people to stop burning their trash is still a fight.
In addition, if there were serious injuries here you should also expect some criminal consequences. But if your point was to suggest that they won't hunt you down just because someone said there was mischief here, I tend to agree.
