Large quantity of gil disappeared.

[CKNovel]

Right because the "normal" player put a vendor full of cheap merchandise for millions of gil conveniently where the botter was is purely accidental. If you believe that I have a lovely bridge I would like to sell you.

In a normal scenario, the bot doesn't exist and if the player wants to put the vendor full of merchandise for millions of gils, then they are free to do so.

There's nothing against TOS to put your vendor in a specific spot or selling overpriced items.
That the bot exist or not is not the question, it should be straight up out of the equation.

If someone buys an overpriced item on accident, that's their responsibility.
If someone uses a bot against TOS, that's their responsibility.

You don't call the police when you "accidentally" bought a sandwich for 20$ and are refused any refund.
