You know that for a fact? 100%? Wow, even people who monitor servers around the clock with millions of dollars in IT budget get hacked and their password files stolen and subsequently hashed. Your response sounds like a reactionary response with absolutely no backing. I'll humor you though, let's go over my internet status. My username/password is nowhere to be found other than Google chromes password backup and on Elysium's servers. None of my other accounts on any other games, bank accounts, emails, websites, work connections, etc. have been ever stolen. These accounts have actual value and get used significantly more often across multiple computers. Most of these accounts do not have 2-factor authentication. Google's password storage is used by hundreds of millions of people and they have millions or even billions of IT budget to protect these passwords. Elysium does not. Occam's razor brings me to the conclusion that Elysium servers have been hacked, password files have been stolen, and are currently being decrypted by people who wipe accounts clean.
No company/game developer ever admits that their security was breached and most people don't even know when it happens. You won't change my mind on this without some actual evidence. In case you don't believe me, here is a video showing just how easy it is to decrypt passwords once you have the necessary files.
