Offense is taken, not given, young'in. The mods speak informally because they're not paid guards, they're more like volunteer bouncers. If they tease you or are irritated by you, they're free to share that. What they do with their powers matters a lot more than what they say.
Nobody in the Murder group asking questions here was, in any way, shape, or form, repressed or given cease & desist orders. Y'all were free to speak your minds, and the mods are free (as fellow users) to tease or show irritation. Trust me, this kind of jibbing isn't exclusive to the murder group. Browse General Discussion for a month and you'll see plenty of it. If they really meant to disrespect and offend you, they'd be far blunter. Trust me.
