How am I just now noticing that D3 password isn't case sensitive?

I'm not sure if this is available for US accounts, but there's an additional SMS alert option on my EU account that should send out alerts for when any security options are changed on your account whether or not you made them yourself.

I'm not sure how much help it would be use in an actual case of account hijacking, but at least it's there and enabled on my account the second I noticed it.

Yes it is available on accounts here. And unfortunately a lot of players are thinking that this counts as having added some form of security for their account and are reporting that they have been 'hacked' when this will not have helped stop it.
