Why remove?
Most people will not report in sleeks locations and "secrets". It is easy to maintain. Add alias|button on turning log off.
Output system will filter "events" by percentage and count. So oneor two entries of "secret" things will not be displayed.
Moderators (VIPs?) will be able to "View Low Count Entries" - player corpse loots, player killing, wrong entries. The check it and press "delete".
It all depends on interface and usability.
