Simply for bad words turn them into asterisks for “chat filter”. This is how Classic used to play. Right now forum simply won’t let you post anything unless you clear it out to PG-3 level of Ned Flanders. Many of us talk using language that apparently is “not allowed”. This is definitely not how classic was.
They also let half the index be cluttered with guild advertisement. You can report these threads all day long if you want, but they don’t do squat about it. I’m tempted to start making my own, like several per day, just to waste more space. Maybe then they’d be inclined to finally clean this place up.
Until they add a Classic guild recruitment forum, it is understandable for people to post classic guild recruitment adverts on the classic discussion forums imo.
The forum filter is not even remotely limited to cursing. This forum filters and censors completely benign words simply because a certain part of the culture considers them politically incorrect.
