Perhaps it was just the reminder that I got from your link of the unpleasant associates who followed me here. Maybe just the ability to ban posters from a thread would be sufficient, without the other problems you mention. If this facility was known to exist, it might be enough to prevent unpleasantness, without actually using it. Sort of like the fact that a private club can kick out an unpleasant guest prevents a lot of folks from getting unpleasant.
You are awfully serious tonight! Did you ever get your computer fixed so it would play the movie right? I think I am going to watch it when I hit the couch.
My cat needs to go on a diet. I leave a window open so he can jump in and out... he gets out just fine, but he is starting to not be able to make the jump to come back in... He just slams into the wall too short to make it, and slides all the way back down, screeeeeetching with his claws :~)
