Correct, the issue is not with players being Turkish or from any other country that's not allowed, we jail / block users for flooding chat in languages which are forbidden in public chats.
You may, of course, speak whatever language you like in your clan / alliance chat as it won't bother players outside your clan / alliance. I'd say even party chat too..
there's no issue with that, you may be a Turk and access the server through a different country and as long as you type in public chats in english or Spanish, it's completely fine.
