I gotta say giving warnings for posting in caps is like bookings for taking the shirt off after celebrating a goal, it's idiotic. Of course it's not nice to have the posts in caps
but very few people actually post consistently in caps à la Vinman, so when they do post in caps it's because they have something special to say. Which is rather understandable in match threads. Otherwise they can post "we scored!!!!!!!!!" in lowercase, which ultimately makes very little difference, cause the message is the same. It's not like you save space by replacing ascii characters.
Anywho: mechanical sanctions of uppercase posting is dumb and you know it.
