The fact that the idea you propose is like using a nuclear bomb to swat a fly. Most electric companies have literally billions of dollars of investments in the cities they service. They're not going to abandon that over a 3 or 4 cent a kilowatt hour difference that they could only use on a very small minority (those who generate their own power) of customers.

Not really. The standard electric meter runs forward when you're buying electricity, backwards when you're selling electricity. With a standard meter, the company can only tell your net energy use. If you use 100 kilowatts, and put back 95 kilowatts, all they see is 5 kilowatts. There's no record of when each kilowatt was used, or anything like that.

This assumes a standard mechanical electric meter, which is what is in something like 95% of residential homes. Digital meters can keep track of when you use, and meter at different rates, but for the most part they're only used by larger commercial power users.

Further, several states forbid the electric company to buy from consumers at a lower rate than they sell to consumers.

Not long after being disbarred, Ol' Jack spammed the entire membership of the Florida Bar (all Florida lawyers) asking for personal stories about how other members have been "unfairly" targeted by the Florida Bar. I presume he wanted to start some sort of class action suit, but I haven't heard anything further about it.

Reading carefully, they'll obey any robot.txt rule for "*", googlebot, or (yahoo) slurp. They apparently didn't feel it necessary to have their own robots.txt identifier so you can block just them.
