On the other hand, Helen Goodman, MP for Bishop-Auckland, is a moron.
Andy Smith, an internet security chief at the Cabinet Office, said people should only give accurate details to trusted sites such as government ones.
He said names and addresses posted on social networking sites "can be used against you" by criminals.
His advice was described by Labour MP Helen Goodman as "totally outrageous".
Ms Goodman, shadow culture minister, told BBC News: "This is the kind of behaviour that, in the end, promotes crime.
"It is exactly what we don't want. We want more security online. It's anonymity which facilitates cyber-bullying, the abuse of children."
What a fucking idiot.
Giving a fake date of birth to some e-commerce site that has no valid need for my identifying details and just wants to send me marketing mail no more promotes crime than buying a pair of tights for my wife promotes bank robbery.
(Aside: this image comes from armedrobberyadvice.com ... WTF?)
If Helen Goodman, shadow cabinet minister for talking crap about subjects she doesn't understand, has her way I'll be forced to show my passport to get a Facebook account ... oh wait, they already think they're entitled to that.
Thankfully until the day I can't open a bank account without a validated faecesbook account I can continue being a facebook-refusenik and give fake DOBs to marketers, and can call Helen Goodman MP a fucking moron (and I don't even need the benefit of anonymity to facilitate doing that.) Moron.
