Re: whitelist. We are still whitelisting. We have internal criteria when determining eligibility for the whitelist. Our internal criteria center around the bot being a proven good actor, number and quality of messages sent, and security of the bot account. If you don’t meet the criteria, you won’t be put on the whitelist. Realistically, you shouldn’t be requesting whitelist access until you’ve run into problems at scale.
It’s highly unlikely we’ll document a hard limit on Whispers simply because bad actors would ride the line with spam.
