So a while ago I started a FB Group for people to get rid of items locally. Its become quite popular with over 5000 people on. Now I don't mind running it, but should mention am not being paid for doing it. I've set up quite a few guide pages for use, but am starting to get regular messages about time wasters and for me to sort them out. WWYD? is it reasonable to expect the admin to spend several hours a week sorting out time waster offenders? I have sorted a few instances, but its starting to spiral now and I'm beginning to think actually it's not my problem to deal with, they agreed to buy/sell something, why should I be sorting out two grown ups dispute? Can they just agree not to want to sell/buy off that member in future and be done with them? Am IBU? should I be doing this as the admin?
