If someone cannot be bothered, why should we bother to read what they have to say? I think it is a good signal.
EDIT: plus it is not an allow or not allow. The more errors the more downvoted, so it is a small adjustment.
I think an llm approach could be good. You make suggestions in however insane language and it converts the format to something boring and mundane accepted by all clients.
Some people are to brief, some elaborate more than necessary.
Says who? Having good grammar is a signal that the person cares enough. I am surprised more forums do not use this signal.
It also had me completely convinced that one should only listen to what is said rather than how.
So, (lol) with me you score extra points if you properly em dash but not the kind of points one would want.
So allow only LLM generated posts?
