I have already reported two live porn/sex feeds. They don’t respond to the reports. That is the problem. If they are going to have this function, they will have to police it 24x7.
It took FB 2 or 3 days to delete a death threat that I received a month or so ago. It was during that time frame when they were openly threatening electors, and I responded on a thread about such a story. The egghead that posted decided that I and my right-wing friends from middle America needed to be killed too. Words to the effect that they would be after "us" when they were done with the electors.
Naturally, I reported it to FB. Their first response was to claim that it didn't reach the level where they'd need to intervene, but then they reconsidered the next day and removed the errant post.
