Long story short: my friend got their account hacked recently (who is our FC's leader) and the hacker utilized the group's FC chest to instantly transfer the 50+ million gil in my friend's account to the hacker's alt in one go. (how it worked: FC's membership is closed -> used hacked account to reopen membership --> hacker's alt joins membership --> hacked account puts all the gil in the FC chest --> hacker's alt signs in and takes out all the gil in a singular transaction).

The request is this: can there please be some sort of implementation that any new members that join an FC is auto-locked out of the FC's company chest for a minimum of 7 days? Regardless of "ranking" or authorization settings? Or even just lock them out of general FC stuff till a grace period passes (e.g. 7 days)?
I mean of course it's not going to stop hackers from stealing other people's stuff or gil via other ways, but why not just make it harder for them? I mean even if they go through MB at least they lose some of that gil they're stealing via tax. But in its current format, the methodology of theft takes less time than it does to file a "I've been hacked" report and I'm hoping that there might be some sort of remediation to at least try and slow it down.
