It’s worth noting the staff that usually monitor this forum are at GDC, so they are gonna be slow to reply.
The primary problem with whispers is not the amount we send but the fact that we either send unsolicited whispers (the bot starts the conversation) or most of what the bot says is identical to it’s previous message. So it’s tripping the filters.
Sure taking stuff outta chat is great coz it’s repetitve spam. Should it go to whispers? Probably not, as again same problem.
You’ll get more mileage if you users whisper the bot and the bot replies to the whisper, that if the bot replies to a chat command with a whisper [citation needeed]
