You guys haven't made a selection yet. Just take a 1 - 4 weeks to secretly monitor people on the server and see who is on the most and see who does the best job of keeping the peace and upholding the rules and see if they want to be a Peacekeeper, looking at multiple players of course making sure you have at least 2 as the minimum you want to ask to be peacemakers. I don't see what the big problem is unless you're already doing that, in that case forget what I just typed.
