Even though there is a mute button it seems like a waste of energy. So much people are spamming inappropriate sentences. I feel like they should be banned from talking for a day or longer.
Thank you very much for supporting Castle Clash. We are still in the process of upgrading our chat system but are currently unable to resolve this issue. Until we have a solution, we urge you to ignore these players if you encounter them in the game. Once our Chat system has been upgraded, we will be able to severely deal with vulgarities.
