I don't believe you. That's not how they operate.

First, before offering you anything to such a thing, they get you to FIRST sign a non-disclosure agreement. They'll even pay you to simply sign one just to hear their offer. If you do so, only then will they tell you what they want you to do.

At that point, you won't be able to tell anyone anything. If you do, the rest of your life will be financially ruined.

Seriously, nobody solicits anyone to do an illegal, immoral, or incriminating thang without a signed NDA.
