I just realized something extremely funny.
GEEGA dismissed the obvious solution to the merch problem, just having people submit their orders of unfulfilled merch, and claimed that she "needs the backend data". Well, you can obviously just wait for shit to ship (which takes a week at most if it's not international), and then do it. But she thinks so lowly of her own fans, people who paid out of pocket for her merch, that she's worried they're game the system to double-dip and get free merch. The majority of the problem is her own invention, if she was willing to believe that most of her fans were decent people who aren't going to scam merch, this entire issue would disappear.
