@ Aodhhan ... Re: @Sane ...
You really are dense... so I'll dumb it down for you...
Breeches will happen. However, you have to ask yourself what the crooks gain by having the data?
Hint: Identity theft .
If you make it impossible for them to open up a line of credit... aka stealing your identity... then the data is worthless for the criminals.
You remove the value from the data for the criminals. However, you remove the chance for the credit unions making $10.00 per account for the privilege to 'freeze' it.
As to the database breech. there are other things that they could do, and that is a different topic for discussion.
