Just delete the group and say: "It violated our terms of service". That's probably also a lie, but at least it's a little less obnoxious.
The airline employees let him do it, and just repeat to us: "Sorry, he's business class!" He gets served first, saving literally hours compared to joining the back of the line.
At least they were honest.
But emotions of the crowd are understandable, so airlines usually have separate line/service for buisness class
Possibly even ask for their phone number.
Though it's tempting, don't message them at all. Just hang onto it.
Only use it to if your community is banned and you need to start over somewhere else. Then email/text them the location of the new community.
I suspect people do this with Twitter and other social media accounts as well.
I suspect you can do the same thing with groups. For example when WSB went down there were already backups within minutes.
