WhatsApp - deleting unwanted messages from one user

The suggestion was to have a second whatsapp group to which the person under discussion was not invited; difficult to see that as an acceptable solution for adults.
And yet some form of shadow banning/ghosting seems to be?
deleting messages has caused umbrage, I can't kick them off (though sorely tempted)
What I'd really like is a Gmail type spam filter for WhatsApp; I'd even pay for it at this stage.

Yeah. Much better to introduce new rules to hide behind than to confront the individual directly.

It’s a WhatsApp group, not the UN. Just tell the person they’re out of line and to back off.
