As a mature person who wanted to express frustration, typing "fffff" seemed perfectly acceptable. A milquetoast, innocuous hiss. Being busted for that makes me paranoid because if that's verboten, what's next? What if I use a grawlix? Will I get punished for something you'd read in Beetle Bailey? It's so extreme that I'm left to assume that I'm not allowed to be angry, disappointed, annoyed, or upset at any time on the server.

I understand your reasoning for not wanting to publish a list, and to some extent I agree that people would try to subvert it (which would no doubt result in a manual report and punishment because the community here is tightly knit and active in reporting shenanigans). But if it won't be published, can the G-rated filters be trimmed back a bit? I would feel a lot less anxiety and would be more comfortable talking to people if I didn't have to audit every sentence I write, no matter how calm and neutral I am.
