I see that everyone is agreeing with dcc, maybe even a bit too vehemently. I would like to bring a couple more things to light:
Mods don't get paid, everything is purely voluntary. Other than the power to delete/lock/edit/ban on an Internet forum, there really isn't anything else going for it.
And not everyone can be trusted to be mods. And everyone who has been picked for moderatorship has the sensibility to understand and appreciate the 'common sense' aspect of the CoC and did what they believe was right.
If it was hard work by you to answer a question or a serious post on topic, it would never have been deleted in the first place. Otherwise, ask yourself why it should have been there in the first place. But if it bothers you enough that you have to go to the argument's most basic elements, to compare a pruning process based on common sense to Nazi Germany, then please, get real. Maybe it's time to move on.
I do not quite understand why this topic evolved into an argument as seen, it is a good suggestion, but probably not doable considering we are using SMF.
