Actually, that's not a bad idea.
If enough people just added email@example.com to their emails, and (say) once a week dumped a log of their browsing history to a file and emailed that, plus a log of their phone calls (most mobile companies let you access it online) it wouldn't take long for something to break.
Obviously they'd try and prosecute under under some sort of harassment law, but they'd have to argue that they didn't need the data (as they had it already). There would also be the terrible niggle that somewhere in that mound of data there really was something of value.
It's such a good idea, I might contact my MP and ask if they can supply the correct email address.
After all, in these times of austerity, it's only right we should help save them some money.
