I believe that the swear filter is in place to reduce the amount of bullying or harassment you may see out there, instead of trying to protect anyone from harsh language for the sake of protecting it. In this regard, I believe it will be very successful! However, I also feel like bullying will happen regardless, so to restrict a wide variety of swear words would ultimately feel a bit pointless.

Still, if it lessened a harassing encounter even by a little, it's worth it. People must be kind to one another!
