General chat is full of people asking for (excuse me) sex, nudes, girls, and so on.
is there anything that can be done about this?
There's a lot of vulgar language in the public chat, can the game developers fix it?
Here is a response from the Moderator Hoodiee about this issue:
"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."
So in other words, your only options at this time are to mute the players by pressing the speaker button to the left of their name, pause the chat, or not use the chat all together.
