Not a bot, but message blocked like one

I do not use a bot for communicating and I did use whispers to contact people but most of them reciprocated the whispers and welcomed them. Now I am getting the “Message Not Delivered” message and am wondering if there is anything to do about that? From what I can tell this happens when either a person is reported as spam, or treated like a bot. I am definitely not a bot and I highly doubt I was reported as spam.

This is the third party developers forum.

We cannot help with you being blocked from sending whispers. if what you send is triggering the spam prevention systems. May also just be a temporary fault in the whispers system, or your target/destination(s) don’t accept whispers.
