Instead of shutting it down couldn't he put the miner in a faraday cage?

Cages only block external em, they don't block internal em from getting out.

Yes they do. A Faraday cage is equally good at blocking radio waves going out as coming in. They don't protect against conducted emissions though - along a power cable for example - so they're not a complete solution.

“Faraday cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with other nearby equipment.”

Sure they do, that's how microwaves avoid heating people standing nearby. However, getting the power in without letting the RFI escape the power connections is the tricky bit.

That would seriously crimp the profit margins, and probably make heat dissipation more difficult.

A metal mesh shouldn't compromise heat dissipation or forced air cooling.

A lot of EM phenomena is symmetric, and this one's not an exception

The notice[1] says it was operating in the 700 MHz band. The wavelength for this band is 42.9cm. A few sources I found (StackExchange, Anandtech) say a Faraday cage is effective with a mesh 1/20th the wavelength.

Surrounding the device with metal containing 2.1cm (0.85in) holes would probably work and only require minor modifications to support heat dissipation.

Side note, now everyone knows Victor Rosario in Brooklyn probably has a bunch of cryptocurrency...

You could literally just wrap it in chicken wire...

At 1155 GH/s, he has probably mined upwards of several dozen dollars worth of cryptocurrency this month. And an extra hundred dollars on his power bill, assuming it’s not included in his rent.
