ISK sink
From Backstage Lore Wiki
An "ISK Sink" refers to any mechanic where ISK leaving a players wallet is not going into another players wallet, i.e. the ISK is being absorbed or destroyed by a NPC entity.
This causes deflation within the economy, as ISK leaves the universe, but the amount of goods in it remain the same (or increase).
Examples:
- Purchasing from NPC Buy-Orders (Trade Goods, POS Equipment, Blueprint Originals).
- Purchasing Insurance (but not claiming).
- Sales Taxes.
- Office Rental Fees.
Common Myths
- PvP (destroying ships) is not an ISK Sink. It is a Material sink because a ship and modules are destroyed, and it is an ISK faucet as the victim recieves insurance. The original purchase of the ship is an ISK Transfer.
