While undeniably an admirable aspiration for kgs users to discuss go, it does not appear to be against the TOS to discuss "off-topic" conversations in game rooms.
Upon indicating this to said admin, I was directed to the main room policy:
Main Rooms Policy
First, KGS is a family-aimed server. The main chat rooms should be appropriate for people of any age from any culture. This mean no swear words, no sex related conversations, references to illegal drugs, etc(see the current Terms of Service).
Second, the primary purpose of the main chat rooms are to help users with go and KGS.
Any discussion unrelated to either go or KGS will be tolerated only if it doesn't interfere with this aim and the first point.
If questions from users are (or would be) flooded in such a conversation, then the conversation should either stop or move to another room.
"Off-topic" discussions, while often tolerated, are not the purpose of the main rooms.
Discussions of a religious or political nature can quickly become heated and disruptive, so are not allowed in the main rooms.
Note: Long discussions in a language other than the room's default language should move to the main room dedicated to that language. This does not apply to conversations with lost newbies.
The admins enforce the main room policy and the TOS. They can terminate a user's connection without warning and they can ban them from KGS. Newbies asking questions are treated more leniently than regular users.
Now, I am not an English major or a lawyer, but I am a native speaker of English. While this text indicates that off-topic discussions are not the main purpose of the game rooms, it clearly indicates that they are tolerated.
The only exception to this is if said discussion interferes with "helping users with go and KGS". Admittedly, what constitutes interference is ambiguous, but it angers me that particular enforcement deems any off topic discussion as such. In all cases I have observed, no "help" was being provided to other users, so the presence or absence of off-topic discussion was absolutely unrelated.
The help page should be updated to correlate with (particular) admin actions: off-topic chat not allowed in game rooms.
Otherwise, policy is not correctly being enforced.
