看一个好玩的对话，理解一下这个词的用法:
Carla :Amy, can I borrow 500 dollars from you ?
Amy : What for ? You just got your allowance yesterday.
Carla : I saw a sweater I want to buy.
Amy : No way. You still owe me 200 dollars.
Carla : If you don't lend it to me, I'll tell Mom and Dad that you cut class last week.
Amy :That's blackmail ?
Carla : It's not blackmail. It's information control. You pay me, and I control what I tell Mom and Dad.
