Warnings aren't accompanied by notes, but bans should be.
Regardless, what's overzealous about it? What do you think can be done to improve the quality of the mod team and moderations? Regarding free dialogue, how are things currently restricted in terms of what can/can't be said? Your feedback will be useful in this.
I'm not sure what else to say. Mods do too much moderating. Like I said, I don't even know why some of these comments are being moderated. I see a note, and can't see anything wrong with the comments.
