What is the most unethical offer you have gotten?

I woke up this morning to an offer about adding an SDK to my app which would monetizing the users idle device resources. Apparently they then use the users computer as a proxy and sell that as a service to other people. That's just all kinds of fucked up. I'd rather make zero money from my app than adding some malware like that to it.

That made me curious about what other unethical offers all of you may have gotten?
