For a few years I've had a couple of gripes on the subject.
1. People who expose themselves to personal risk (especially kids) by giving away personal information to total strangers.
2. Mass hysteria about anyone knowing personal details.
At both extremes there are risks:
The 12 year old girl who meets her online 15-y.o. dream lover only to find he's Mr Chivers, the creepy 40-something janitor.
But recently Jeremy Clarkson (Mr Self-Opinionated-but-entertaining git from 'Top Gear') posted an article in his Sunday Times column about our unreasonable panic about data loss. He argued that having your account details is no biggy. Without passwords and personal private information (name of 1st primary school teacher, 1st pet etc.), all they can do is pay money into your account.
I was cheering him as I read it. Yes! Stop this press-induced paranoia! Debunk these conspiracy myths!
To prove his point, he published his account details in his Sun Column ("All you'll be able to do with them is put money into my account. Not take it out. Honestly, I've never known such a palaver about nothing,"). I was quietly respecting his convition, until I read this.
