You had me, until the end where you indicate to inform the admin of a problem post(er). You do realize that the user can block the user and/or the instance, right? That should be the avenue, don't burden the instance admin with this - They have enough issues with running things.
This is the way it's usually done on OpenSoftware communities. Many of us old timers resent the Birdsite hordes coming over and demanding change. If they want change, then stay on the Birdsite - it's probably far safer than Mastodon. Quite frankly the experience on the Fediverse is more REAL life than the walled garden that is the Birdsite. I've been on the Birdsite since it began and even though I post about geopolitics and war, have never been bothered or let other people bother me. I don't want a nanny to set the rules for me, since I can do that myself.
