Stop being obtuse. The behavior eBay engaged is covered under laws criminalizing harassment or stalking. Try holding the .gov to the same standards and see where it gets you. Even if there isn't a legal carve-out it will be a much more uphill legal battle and the other parts of the .gov you have to deal with along the way will try as hard as they can to avoid enforcement actions against whatever part of the .gov is abusing you.
