"Quest info" is a general term referring to any information
about solving problems within a level quest or area quest.
This includes things such as where to find keys, how to open
secret rooms, what to ask NPCs about, and so on.

Giving out quest info on public channels is not allowed, as
it could spoil the game experience for players who would prefer
to figure it out on their own.  However, sharing information in
private conversations or tells is allowed.
