Today I came across someone (Jazmine MsClumpsy Tucker) offering a banking service at Camp Icarus. What you had to do was 'deposit' something to the bank, items or PED, no matter how much it is worth and they would give you 1 PED each day in interest. I have not tried this service so I have no idea if it actually works, but I would like to remind people that all trades are final and that handing over any item to somebody else does not give those people any obligation to give you back your item, let alone give you any extra PED.
I would ask how long has this banking service been running and who last deposited in this bank and where the conversation took place.
Not to mention that any banking activity outside of the existing system was strictly prohibited after introduction of the banks. Even if it wouldn't scream "scam" as it is, you'd surely lose your money upon the locking of the "banker"'s account.
I seen this avatar often at the baby oil rig. Was disciple to some "heavy hitter" if I recall correctly, don't recall his name tho. Will see if I can remember it.
