One person will have to control it. As pasquale said, sharing it comes with the risk of everyone who touches it getting banned if one of the people does anything against the rules. I personally don't believe in the idea itself and have only ever seen one system executed with complete fairness but even with a fair a system as possible including a lot of work and spreadsheeting, at some point, as people quit the game and leave gil behind in that bank, there is one person who eventually owns it all. I believe in free lot and rng gods on money items. But everyone has their preference.

Farside has had to invest gil into RFK’s bank that kind of nullifies what he gets to play with in terms of unclaimed money. Over time people occasionally don’t turn in saleable split items, and he has had to compensate LS members for the awol members who never turned them in. Running a bank like RFK does is a bit of work. Maybe Locke can weigh in on this.

No LS bank is perfect. “Fair” is relative. The best we can do is informed consent.

Running a linkshell bank is no joke. Visibility, accountability, transparency, and everything in between those lines are key. Anything you can do in the middle of that to automate the process of record keeping helps tremendously when it comes to the distribution/fulfillment of gil.
