Making it harder to stop than to continue.
Sunk cost is what turns a single loss into an escalating one, and it is the reason victims often continue long after an outsider can see what is happening.
Each amount sent makes the next refusal more expensive. Refusing does not merely decline a request. It concedes that the earlier money was lost, that the relationship was not real, that the investment was never there. Continuing defers that reckoning, and deferral is easier than acceptance.
Operators do not need to apply this deliberately, though many do. It builds itself, and the escalation frequently appears to come from the victim: they decide to increase the position, they offer to send more. That authorship makes the experience far harder to later recognise as something done to them, and it is a significant reason this crime is under-reported.
It also compounds with fees at the exit. Once a withdrawal requires a payment, every further amount is sent to unlock money that does not exist, and each one deepens the position.
The only useful framing is that the earlier money is already gone regardless of what happens next. The question is never whether to recover it. It is whether to add to it.
