I've meet very few people who admit the reason their account got hacked may have been their fault. Yes, sometimes people get unlucky, but sometimes people just invite trouble by sharing accounts, using easy passwords or downloading cracks/hacks which may contain keyloggers.

On these cases, people place the blame either on the company's lack of security or a hacker's godlike ability and swear their computers have stone-hard security.

Not to say the company may not be to blame, or the hacker might not really be good, but it's good to check how much to blame might be yours, least you will be bound to repeat the mistake in the future.
