Tossing my two cents…
If the main staff dislike/hate/etc. they should just say it instead of ignoring said person in hopes they go away.
“Hi so&so, thank you for your interest but you and this game/staff/etc don’t vibe. We hope you find your game in the future. Here’s the door. Bye.”
That literally took 5 seconds to write.
I agree staffing isn’t a job. I’ve always seen it more like having an open house of sorts. If there was someone in your open house that clashed with you for whatever reason, you wouldn’t just ignore them, you’d ask them to leave and if they refused you’d show them the door (banning). 



. I had very much similar experiences or had friends have those experiences with everyone involved.
