Hi Chief,
Clash of Clans has a profanity filter that prevents the use of offensive or vulgar words in village or clan names. This feature stars 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.
I know this feature affecting your name can be very frustrating for you, especially if profanity was not your intent. However, please bear with us as we work to improve this, and I am sorry for any inconveniences caused.
We appreciate your taking the time to report this. If I can be of any further assistance, please don't hesitate to let me know.
Clash on!
