That gets back to "how do you stop them"?
I doubt anyone with a 175w collector or two is going to make enough difference in their electric bill to show up on the bill as a red flag. How will the PoCo catch them? This is just a plug and go "appliance" that is U/L listed.
It would be easy to argue that if the meter never actually ran backward you never fed the grid in any way at all. The net flow was always in.
