It's really simple. The the main chat room, "Public Channel" is for English discussion only. It's a very common practical decision in chatting systems like this one. Meebo is different because there's no moderation but this chat has nothing to do with Meebo.
When you speak some non-English language, chances are the 90% of other chat users have no idea what you are talking about. For them your writing is gibberish, therefore it's SPAM.
If you want to speak your native language, you have 2 options:
1. Use private messages
2. Change the channel to something other than "Public"
Later we will have different chat rooms and I will include a "Non-English Discussion".
I informed you of these rules in chat. You complained about them. I informed you of the rules again. You complained some more. I told you the rules the last time and I'm hoping you will respect those rules. I have no interest in starting to issue warnings and bans because of chat discussion, but don't think for a second that I won't do it if these infractions continue.
The same rules that apply to this forum, apply to chat also. I suggest that everyone reads forum rules (
