Brings that person's real identity in front of the family he his about to join in the future
Things as such should be dealt with just like job interviews:
*The recruiter of the new family can merely contact the leader of the group in which the applicant was previously in, asking the reasons why such member got kicked/banned/left.
This way It's easier to check a player's loyalty without having the embarrassement such players will succumb to with that list.
Plus, the panel is a very handy tool to catch constant rule breakers.
That's merely my opinion, I'd never do such a thing personally, but I guess It's up to each individual.
See you ingame gentlemen, cheers!
