Inappropriate Chat
I don't know if the Hindi version is filtered but the other certainly should be. If you are seeing expletives in chat, you should open a ticket, since that would be a bug. Ideally use the report a bug option in the menu so it can hopefully capture the expletive in the chat window.

Beyond that, you can do as mentioned in post 2 and disable chat.

But please, don't post expletives yourself in the forums.
I am so tired of people writing [removed -- VP] or in Hindi [removed -- VP] in my comments that it irritates me to hell. what should I do to this type of people? They seem to have no manners at all. Writing stuff that pissed me off. I am tired of this type of people. the way they pissed me is very simple. I write a good thing about some topic and they instantly replied me with [removed -- VP] or [removed -- VP].it deteriorate my mood completely and it make me wonder why i am chatting with them
