I have my own domain so it is easy enough to change it if I have to. Then, I would just be giving out the new email to the same entities. My wife uses her email very carefully to a small group of social contacts. Yet, she gets some spam. I have a couple of very seldom used email accounts at my broadband ISP. They are used only for a rare joke email to a friend. They sit there for months without activity other than the occasional promotional email from the ISP.

As it apparently involves sending SMS messages and calls to the phone at random times, it should discourage the use of those phones as detonators for the not-so-smart bombs wearing clothing by duPont. This sounds like a good thing to me. grin

In the U.S., with POTS service, virtually all end-users have basic protection against such 'at the DEMMARC', provided by the telco. There are multiple reasons for the telco providing it. For starters: 1) given a strike on telco wiring, with a surge following the telco wiring into the property, and possibly injuring someone inside, the telco does have legal liability. 2) if there is a strike on the end-user property, the telco doesn't want that surge 'backing up' into the telco system, and blowing out lots of other customer pairs. > >People still complain about their ISP after storms in their area or >bellyache about their "crap" ADSL modems which - coincidently - seems to >either fail or degrade in performance after these self-same storms. The only weather-related DSL problems I've known of were where a multi- pair distribution cable had a moisture problem. After a hard rain some water would get into the cable, and cross-talk issues would go way up. wait a few days, the damp spot dried out and things were back to normal. Well, until the next rain.

The ringer was connected between one of the two leads and the ground stake, not between the two leads. Whenever a thunderstorm was nearby the phone would ring, usually just a 'ding' in synch with a lightning stroke. (actually the phone would tend to ring more after the storm passed over us and was to the east) We'd joke, "Mr. Lightning calling, don't answer it!"

Actually, I'm not as motivated by social do-gooding in this case as my original post might have implied. There is a little corner of the campus here, hemmed in by some hills, that's a dead zone (aka "blackspot") for all the local cell carriers, but still has very good Comcast cable connectivity. As an engineer, I like to see problems solved at minimal cost and maximum efficiency. In this particular case, putting femtocells into the 3 or 4 residences in this blackspot is likely to be not only cheaper and more efficient than adding a new multi-vendor tower, but probably even better service-wise. Maybe I could try to force Verizon (or Optus) to pay for this femtocell, but at $200 I'd prefer to "just do it" myself and get on with my life. (Incidentally, I then own -- and can potentially re-sell -- the femtocell; and there's zero "pro rata" cost for the Internet connectivity, since it's a fixed-rate service.)
