A new scammer list should be put in place either way. You can't just expect people to sit back and do nothing. Like Ameh said, it needs to be purely neutral people who will not take sides. The problem is, it's a lot easier said than done so it will either not be done or it will take a lot of time to sort out.
We all need to drop this discussion sharpish. It got way too out of hand. The thing is, if someone gets accused, you can't not expect them or their friends to defend themselves. It's human nature. Just because it doesn't happen the majority of the time doesn't mean it never will. There's also no need for his hostility towards each other either. .___.
