Honestly, I hope that this post will hit as many vulnerable people and their accounts as possible- maybe it'll give them courage to replace their credentials with secure versions.
You can also add to the story other common mistakes:

• not remembering passwords and depending on browser's auto-fill,
• legendary 'one note for all passwords',
• and the most dangerous - one password for all services. I think losing main e-mail account, bank account, social media and every other at the same time is more scary, then losing only blockchain wallet.
