If thats an open question to the forum.
I consider whispers to be used by two people whom are not bots/automated entities to send a private message to each other, where there is no channel context.
Since whispers don’t “belong” to a channel. When I’m off watching some streamer and someone whispers me going “can I get an unban” I first have to ask them which channel they refer to, for example.
IE: for channel agnostic messaging.
