I can see how if things are more visible, they can lead to more outright complaints. On the other hand, when things are more quiet like they are, it leads to some conspiracy thoughts and quiet finger pointing. So both have pros and cons - a middle ground would surely be best.
Maybe have posts visible in a pending section, and then deleted when decided either way, with approved going to a list like now. Or possibly an overview of the sort of things that get declined for people to have some reference?
