On the other hand... him not being right does not make it FAIR. And that's my point. If this happened to me, I wouldn't be angry at being censored but with all the other versions slipping by, especially in AH where these variations are COMMON and almost accepted as substitutes. Maybe I am taking my personal lens to what the OP was asking about, but that's how I see it.
Any attempt to bypass is not acceptable, including the ones you posted. The rules are perfectly fair. They apply to all. The filter did not trip him up, the common judgment of people in the arena tripped him up. It is impossible to write a filter to catch all, so we have back up systems such as moderators and the report feature.
99% of the time someone comes here and post something like this, they are posting only the final statement that broke the camels back.

Skuzzy walks in my office after I typed above, and also was reading this but we had no knowledge of each other reading.
Skuzzy looked at the logs and muted him. And as I said about 99% of the time, I was correct.
Since you asked it was not what you state why you were muted, but many other incidences that showed up in the logs.
