I do see where people are coming from, but it's still wrong that we have no recourse - if we persistently nag this player to give the items back he can report us for harassment, while se is unwilling to take any action whatsoever.
Locking people out of the chests means that they can't get involved until they are highly trusted which could take years. So that means they can't be involved in airships, or any of the company crafts without levelling the crafters and gatherers themselves - which for a new player is going to take a lot of time.
I mean, this member had been in for months - we really did think we could trust him. And we wanted an environment where people could get in fast with the support of players who are much further ahead.
I also dont see the logic in handing out warnings and bans to people for resetting hunts under "disrupting others game experience", while stealing and dropping isnt considered so?
