Well, here's a mod thing that recently happened to me (granted I didn't get muted over it, but still!).
200 was active, and a mod (I assume) and another player were taunting each other back and forth. Nothing nasty, just normal chest-thumping. I put my two cents in and said "Xxxx, have you been drinking? You're usually more sane."
And instantly got warned for it!
Seriously. 200 is part of the fun of the game (as is cross-country PMs, but we won't go there atm). Mods ARE needed, but if they're going to use their authority to quash something as mild as that, their authority needs to be looked at more closely.
