Be nice.
that message may be completely innocent, only time will tell. That's one of the difficulties with policing content, it's often the character of the person posting that is the real problem, rather than the actual words they use in a particular post.
For example, I just flagged a message because I think the person was being "rude" --- I'm trying to think of a way to read it in a non-rude way but I can't think of any. I think the message I flagged was curt and not helpful. But this is also coming from someone who does not have English as her first language. What do you think, Jack?
How would we judge if someone is being "not nice"? I guess we can always give people the benefit of the doubt.
It's easier to abuse though — what is 'patience' with extremely poor questions for example? 'Tough love' comes under 'Be nice' more naturally.
this is intended to be the only global CoC. I'd prefer for more detail to be applied at the community level if necessary
Might I recommend at about 25k words of *lorem ipsum*? Straight up adding clauses to TOCs later is always rough — even if said changes are well thought out and thoroughly justified. It would be a lot easier to have some space filler here that can be edited to remove at least as much as you need to add.
