I moderate one fairly active and one very in-active discussion groups.

The actual work is very similar, only varying in quantity.

On both groups, there are regulars, regulars with known triggers, casuals who might become regulars, and flamers. The regulars with specific triggers can be progressively discouraged.

The flamers must be stopped hard, or else they dominate conversation for days or weeks, making everyone else unhappy. You can give them a second chance, but not a third.
