We need to the ability to BAN from GROUPS. Ejecting spammers and trouble makers simply allow them to re-enter a public group and cause chaos. And if they are revoked chat, all they have to do is close and re-open it.
Spammers simply can just close/reopen anything and continue to harass large group's. We need the ability to ban, otherwise the entire Group System is useless.
Currently there is even no need to have a Moderator status because a user can mute another, but the muted simply close out and reopen the chat and can continue talking about sex/spam/3rd party advertising and more.
I think I speak for the entire grid when I say,
WE NEED GROUP BANS! EJECTIONS DO NOT WORK!
