So many people are using this app to sell things. They put $0 on their post but in the description say the prices for their items. It is a flagrant violation of guidelines yet non of the posts ever get taken down. It is now at the point where there is a 30% chance it is not free at all. I try to correct as many people as possible but many are hostile and tell me to mind my own business. Why is no one monitoring this?
