I'll second what Bill the Lizard said in his answer.
I will add an example though:
Often times moderators are compared to janitors. I'm seeing this more frequently currently since there is a moderator election going on.
So, lets say there is a janitor at an elementary school.
On day 1 the lunch menu is pizza, chips, and soda. Table 23 gets tipped over by a bully in the 5th grade and 8 3rd graders lunch trays get spilled on the ground.
The janitor goes and cleans up the mess.
On day 2 , there are no big messes.
On day 3, the lunch menu is extra sloppy joes and a snack pack (either vanilla or chocolate). On this day, boys at table 11 started throwing some plastic spoons at the girls at table 2. The girls got upset and one girl took a big fat sloppy joe and threw it at a particular gentlemen at table 11. Then that little boy started crying, but his friends all grabbed what was remaining of their sloppy joes, and chucked them all at the one girl at table 2, however, a lot of it missed her, and also hit innocent civilians at table 5, 7, and 9.
The janitor went and cleaned it up after lunch was over.
So as you can see, the janitor does not care what type of food is served at lunch, if the food makes a mess on the floor, he goes and cleans it up.
