They have been addressing it and have said they can issue game bans for violating the policy if they feel like it went beyond what they consider a joke/attempt [quote]For what it's worth, any player who sees their name has been changed to Guardian should consider themselves lucky, our CoC states that we hold the right to remove the content and the player. The Guardian names are our way of saying we know you think it's just a joke, but most people probably wouldn't agree.[/quote] https://www.bungie.net/en/Forums/Post/262695853?page=0&sort=0&showBanned=0&path=0 The problem is they don't automatically Guardian names that existed prior to the filter being updated to include it - likely in case they make a mistake on the filter and incorrectly Guardian players. Once the filter gets updated it stops people from being able to change their name to it in the future and then they work backwards with removing people names - further updating the filter if someone they find has a name that should be on it.
