So when I find my rival is visiting the USA, I can set up a linkedin with his name on and write "Working in Seattle for a few months as a plumber. $$$ is good here!".

And they'll be arrested?

I am not a lawyer but that could well be a federal felony.

Maybe you can prove them in person it is not your account, but that mean you would have to get a real visa not an ESTA.
