The government really don't get it. They keep going on about "buttons" to report sex offenders online, registering email or IP addresses or any other crap which *will not* work - I've countless email addresses, some traceable to me, some not - nothing online actually requires you do give a real name, address or anything else.

 

You register their email addresses, they just get another. Register their IP (few ISPs even give static IPs) they'll use a new IP. I use O2's wireless broadband, half the time geolocating services claim I'm in Germany.

 

No; the *only* way to deal with these people is to lock them up permanently. If they are in a controlled environment they will not be able to re-offend. But of course, the lawyers won't allow that...
