The folks moderating SE are very pedantic about the wording of passages. Once I called SE a "forum", and I was politely told not to call SE a "forum". I would really hate to be a person that is not very fluent in English and trying to interact with SE.
One of my latest questions got as first comment : "Please use English punctuation when writing in English."
Certainly polite but a bit jarring as a non-native speaker that feels fluent. Also a bit nonsensically-bureaucratic : I made the mistake because I didn't know any better, after the comment I still couldn't correct the mistake because I still didn't know any better, I wasn't even sure what rule of punctuation I had wronged.
I would've preferred a direct edit instead of a comment prompting though I guess that can be seen as worse by some people.
Yeah exactly, in French for example you put a space before a colon, a question mark, exclamation mark, while in English you don't, it is quite hard to spot for a lot of people.
OP is about someone who is extremely fluent in English, an expert in the eyes of the community, who was kicked out pecificaly for the sin of trying to interact with SE in fluent English.
