Account email registration

Fairly new to this and didnt know where else to post but why are accounts with no email attacked valued more than thos that have a registered email? Along with this if purchasing an account with an attached email how can you secure it?

 

I wouldn't say accounts with no email attached are necessarily more valuable than accounts with ones attached. Everything regarding the two is subjective. In fact, I'd personally rather buy an account in which the login email matches the real email account & the sale comes with the original email. From my experience, you have a better chance of a recovery if you have access to the email that was first linked to the account AND matches the OSRS login.
