There's nothing stopping you from doing that. You'd soil a blossoming business relationship that's paying $20/day for minimal effort. You could also copy our keywords, ad copy and create your own campaign with the same designs that we're running. I wouldn't want to compete with us but you could try it. Google is a long game. If you can sustain that then by all means, otherwise I'd stick with the $20/day.
Then what's stopping you from posting your "legal" business in the original post.
You are caught in your own lie now
It's the responsibility of the account holder to vet the ads being put up.
So you do agree that it will be the client's responsibility for whatever scam you run 
This is what I have been saying, to minimalize the consequences they should verify your identity or post your so-called "legal" business here to corroborate the ads.
Good luck conman
We're going in circles now. If I am running a scam then the client should not be my client and end the campaign creation right there...
