We mod with a lighter hand than many charge us with. It takes a lot to push us over the top for many reasons. One, we may be gathering evidence to make absolutely sure. Two, sometimes when other FReepers call them out on their liberalness, it strengthens their arguments. Three, sometimes it is hard to tell when someone is being factious. Four, sometimes we like to see them squirm. And finally, sometimes we just happen to overlook them. We are only human (that we let you know...)
facetious :D
