In response to Mike's observations,
Being in groups and knowing what they expect is a personal responsibility. Otherwise, just join the cookie cutter (Broad) ones. Being overwhelmed with rules is because someone is simply in groups they shouldn't be in. Groups are about everyone understanding what membership is about.
This leads me to believe that there should be a limit to how many groups an artist should be in. Perhaps there should be an outlet for ADMINISTRATORS to be able to point out those who join who do not follow the rules. After a certain accumulation of rules trespassed the offending member should be suspended from joining more. Should go for Contests as well.
I do agree that folks should "Only place things in groups that your image fits, same with contests."
Administrators are volunteers who "generally" have your interests in mind. Is it a crime for them to expect you to have "theirs" in mind?
