It's one of those things that occasionally comes up like this. We had a time where people were just pushing those buttons in a frenzy of good natured ribbing. Occasionally someone will use the smite button in a churlish way, instead of just disagreeing with something, but I've found that to be rare. I'll applaud someone for good arguing, rules clarification, organizing of events, or whatever, but I think I've only hit the smite button once when someone made a disparaging remark about our community, and on the occasional spammer. I don't waste my time with the spammers anymore except to report them.
If it makes you feel better, y'all can smite mine all ya like. My karma has taken such a turn lately I could use a reality check.
