Well, it happens to many companies these days. Very hard to stay on top of IT security when the attackers are very clever and cunning.
I trust a company more that has actually gone through a data leak as they would've gone through a review and hardened their systems etc.
If someone is very concerned about their data security, then don't enter competitions…
DigiDrrect had a major data leak last year.
