How many accounts do you have here, 5?
I'm not sure, I think I have a total of 3.
Before we get into multi-account discussions, let me just clarify.
I've lost access to a lot of my emails which means retrieving lost accounts is hard, therefore feel free to remove old accounts.
One of my first email accounts was either; 1) Hacked. 2) phished. I attempted reset password and boy, that didn't work out to well.
Other accounts, I'm not to sure, But I'm pretty sure this is my 2nd account, other account was 'mfw' so feel free to delete that. The email to that account was registered under a personal domain which expired, I assume I've got another account in my hotmail account which I didn't bother with.
So, let's just say; This is my final account. I do/might/have had other accounts which I've "honestly" lost access to via email deletion.
Not valid enough for you?
