IMO the reason why that happened is because OP wanted to be too anonymous.
As far as I know all money flows above non-trivial amounts have to be attached to some entity. Gift cards allow to bypass that, since, well - they can be bought in store for hard cash.
2000$ is non trivial amount (and honestly, I'm really wondering why one would have that much, that's for digital content only, right?) - if that's OPs primary way of adding money to the account it stinks of a laundry scheme. Buy gift cards at kiosks, buy obscure DLCs, cash out.
Probably the way out would be to provide full paper trail. Not sure if Apple even can ask for it, though. As someone else wrote in comment, getting on the bad side of the fraud detection tough nut to crack.
