I got a similar warning, in which I used a hyperbole to express frustration at the lack of color individuality for clans, and I said "they should hang whomever decided this would be a good idea", and while to me it was a clear hyperbole and not an actual call for lynching TW staff, I got a warning for that.
Thinking back I can understand how editing my comment and giving me a warning was aimed at preventing other people from following the same tone as said people might not mean it as a figure of speech.
I don't know what you said, but it looks like the same situation.
