I'm not sure we know which email accounts were hacked excepting the account holders name?
Pinto hacked everyone he could, there would have been dozens, hundreds or thousands of others he failed to get into.
Der Spielgel had to invest in expensive specialised software which trolled through everything looking for links and chains of emails and associated documents. Yet they only published 6 emails from 5,500,000 stolen just from ourselves. Depending on the source you believe he eventually turned over 70 million stolen documents from all different hacks. Lord knows what he hasn't turned over.
Most of those he got into would’ve offered nothing of interest based upon a few basic buzzword searches and it’s highly likely even Pinto hasn’t read 99.999% of the emails he stole.
