Is this really the right course of action though?
I do agree that flower needs to work on herself especially when it comes to emotional self control
But, I have a question - Can you clap from one hand?
She has issues with some and they have issues with her.
Imo, you should first explore having a group chat with them together and try to bring them on same page.
They all are part of this community for a long time now so why don't have a chat with them - and, help them reach to some understanding with each other?
And, if someone is unwilling to come to understanding or doesn't put efforts to make changes in following games, then you should go for the ban
