And this is the problem, Samboll and Handysolo - it isn't just admins who get to see this screen: ANYONE above the level of basic "subscriber" can access the email addresses from the "comments" tab, including "contributors". So it isn't just admins. This is a huge problem for multi-author blogs, or those who set the default level of new members to "contributor" for whatever reason, anyone who registers can see this stuff.
Try it on your own blog! Set up a dummy user as a contributor and go and see all the stuff this person could find. It is NOT what a mere 'contributor' should be able to access.
I would argue that even editors have no requirement to view the email addresses of commenters, though this is debatable, but the 'contributors' and 'authors' definitely should not - they cannot edit comments, so this screen should not be available to them at all anyway.
Please can you help me to remove these capabilities, I run a multi-author blog and I'd like to let new authors get involved straight away as contributors, however, I don't want them to be able to access all these email addresses, this gives them huge potential to spam all and sundry.
