I just ran into a problem with the vulgarity flag feature. It reveals whole messages therefore if someone breached SMA on dwilight in a message of a sensitive nature flagging it would reveal that information to people who aren't supposed to know about it in character.
I often report sensitive messages as vulgarity as a way of leaking them out around the continent without incriminating myself.
It's a clever way of being a major leak and damage to a person or realm without almost no risk to yourself.
