We've now added member moderation on Radius. You can require approval for new joins, remove a member, or ban someone from your group.
How to use it
Go to your group's Settings → Members. From there you can turn on Require approval to join group, and approve or reject pending requests.
You can also remove a member (they can rejoin) or ban them (their posts in the group are hidden and they can't request to join again).
You can read more in our docs on member moderation.
