Allow group owners/officers to ban avatar(s) of their choice from joining, or re-joining, their group. I`ve had it with the spam induced cat and mouse games - Ejecting spammers only allows them to rejoin and continually spam and harrass group members and there`s nothing group leaderss can do about it. It`s illogical and time consuming to eject someone from a group, only to have them re-join as many times as they`d like and continue their problematic behaviour. This is ridiculous, let`s put a stop to it.
