Q:

Non-English Discussions in SE Chat

This is a follow-up discussion on this recently raised question, specifically about Shog9's answer. 
This part in particular: 

If concerns are raised over the appropriateness of a room's
  conversation, then either the conversation or the entire room is
  subject to deletion.

This effectively equates to a soft rule of not allowing non-English discussions at all, or at least it allows singular users (via flagging) to shutdown non-English discussions whenever they see fit. I think that's a dangerous precedent to set (that we don't care about the merit of the flag, the fact that it's non-English text is enough to validate it).
I think SE either needs a solid policy (like prohibiting non-English discussions period) or solid guidance (only validate flags where you can discern if they're valid or not). Currently for innocent discussion people can trigger automatic chat bans, or for offensive discussion nothing can happen at all.
I think a clarification of policy is necessary for this.

A:

The choice here isn't between carefully moderating non-English rooms and shutting them down.
It's between unmoderated rooms and shutting them down.
There are... A lot of languages that aren't English. Way more than three. Expecting moderators or even 10k users to be able to interpret some abbreviated slang in an unknown language properly is... Naive.
I know this because we tried it for years and it ended badly. Folks were being put in real danger because we weren't stepping in. 
So this is the lesser evil. It's an English website, expecting English in chat is not unreasonable.
Up for discussion: Can we be more than just less evil?

A:

The problem with "only validate flags where you can discern if they're valid or not" is that it allows offensive content to be obscured by language.
It's a privilege that non-English rooms are allowed.
If a room causes issues (flags), that privilege can be revoked.
A solid policy would help clarify the process to users in chatrooms like these.
Steps like these could be considered:

Non-English chatrooms are tolerated.
On a first "incident" (Flags), the room receives a warning.
On a second incident, the room is locked. Room owners can dispute the lock by contacting the moderator that locked the room.

(This is just a rough idea)
