I dont know if anyone has already presented this idea or not. But all the pools should have feedback system that the users who are considering joining the pool could read other people’s opinions and reviews of the pool. Especially if there’s a fee for joining the pool. Every left review should be rewarded with some amount in GUP (aka initiative).
Basicly system would be something like booking.com or airbnb uses. Only verfied user (users that at some point have been members of the pool)
