FF14 is not made for hardcore players.

It's an additional countermeasure for profanity. You don't just have a singular deterrent. If they used the profanity filter as the singular means of deterring people from it, without the inclusion of rules or consequences then people will only seek for ways to bypass the profanity filter, be it with other slurs or alternative and creative use of words or structure. I've seen plenty of people attempt to go through a profanity filter. Be it within this game, or other forums and games,

Profanity filters are not without fault, that is the point. Once again, not intended to be used as a singular deterrent.

So because the filter can be bypassed by creative individuals, which I imagine is a very small portion of swearing that occurs in-game, that somehow makes them not efficient? I'm sorry, but that sounds an awful lot like grasping for straws. This is equivalent to someone not getting vaccinated because it's not 100% effective, then complaining when they get hospitalized.
