Interestingly, I've been in a situation that basically mirrors that comic.
I was offered money for someone's private info by people intent on finding and hurting that person. I was homeless, and desperate. I refused the offer. They doubled it, and again I said no.
They raised it again, to a level that would have gotten me out of my unsafe situation.
No!
It's something I try to think about whenever I'm feeling worthless.
