I am weakly in favor of the limit, because this is not a chat platform and people should put some thought and effort into their posts and comments.
Also, is this related to this recent comment of yours?
To be completely honest I think that comment is below the level of quality that I would like to see on this platform. I don’t think it is adding anything to the discussion.
But that would indeed confirm that the limit is easily bypassed by just adding a few fluff words.
