I think it has to do with reputation and the cost of entry.
I use to play on a minecraft server that had a griefer trap right at spawn. The server automatically monitored any attempts to grief and auto banned griefers while sending a server wide announcement.
When the server was wide open and anyone could join, the ban notice would spill out so fast we had to get an admin to silence it.
When we swapped to a whitelist that required a person to submit an application and wait to be approved, messages were rare. Only one or two a week.
When we swapped to invite only, we never had the message go off. Not once from what I remember.
As we swapped between the three states (in an attempt to maintain a certain server population level), the pattern was kept up.
The lower the cost to get in, the more people who violated trust. The higher the price, the less people who violated trust. When personal reputation was on the line, no one violated trust.
