Got chat blocked for "Code of Conduct" for Innocuous Chat

I responded to a global message about being drawn to so many different builds and got a message that my chat had been blocked for not conforming with the Code of Conduct. Nothing in my text was even remotely offensive. My suspicion is that I used the phrase “alt-itis”, which I have seen being used in MMOs forever. Now all of my global chat seems to be suppressed.
