Clash of Clans has a profanity filter that prevents the use of offensive or vulgar words in village or clan names. It does so by using asterisks to star out words or letters in a name that can be offensive. This feature is very important for us as we want to keep Clash of Clans free from anything that would cause offense to players.
In some cases the profanity filter can be a touch aggressive and even star out innocent phrases. Please bear with us as we work on making it better at spotting only offensive words.
