I am suggesting if we can update the forum set up in a way that users can change the email link to their account.
If you (or hacker) can log in your account, you can change the email address connects to your account. It leads to another trick. If you want to terminate your account, you can change initial register email to a random (non-existing) one, change the account password to a random and log out.
I created this topic because I have come to realised that account sold out are still stollen back by the seller for the reason being that they have access to the email even though the account buyer change the password to the account still they can still have access but if we can change email connecting our account after is created, it can minimize scam or stollen account related cases. This change should only be made accessible for the account owner together with strong password.
It can be done by a step above but why do you have to do this if you set up good passwords for your email, your forum account and 2FA for your email too.
For people who are careless with it, I am sure they will not care about changing their email only because to avoid hack. In addition, register email is one of way to recover your account so I don't think it is wise to change it to a non-existing email.
There is (un)official recovery method, by a signed message but email is important too.
It's good to take care of account security because it is good for you as well as reduce recovery burden on forum moderators.
By the way, I think it's better for you to learn about Bitcoin than try to learn about forum rules, trust flags, merit because Bitcoin should be a main reason you join here.
