It would be nice, if the admin/mods can make a vote about the warning before it will be in public. If a mod thinks that someone should get a warning, he clicks on the button. All other admins and mods get an information about that or they can take a look at the "delay"-list. If x mods or y admins vote for "send warning" he gets his warning in his list. If they do not agree, the delayed-warning will be erased.
This is a kind of democracy, isnt it?
