How old is that? I don't remember. This way you should be punished for every mistake you did in childhood
Unfortunately, Trust, especially on the internet, is not equal to every mistake I did in my childhood. It's take a long time to build but once broken, no one is just going to come around and instantly trust you.
The best you can do is offer a collateral.
I believe that a user can change his account details without asking anyone to do or not as I don't have access to the previous email anymore + I have paid everyone's money back as I was busy for some time between.
It could also mean the account was hacked, sold or changed hands. How are we supposed to know?
That's why the text appears in red when both details are changed. To warn users to proceed with caution.
