Ivovic, you weren't particularly helpful.
I was asked by one of my authors on a blog why they could see the IP addresses and emails of all commentors. I had no answer for this, her response was, "well if I can see them, everyone else can!"
I assured her that all 'normal' subcribers cannot view this, but the harm has been done in my opinion, and she has told everyone else that there are security issues on the site.
Yes, I appreciate that you will usually only have trusted authors on ones site, but can you not imagine a situation where you might not? I certainly can.
Here is just one, that I have:
A blog which invites multiple authors, and sets the default level of new members to "contributor" and, while moderating their posts - thereby NOT, as you so inaccurately put it "pollute your domain name with their posts" they are in essence 'on trial' - should they be able to view the email addresses of all your other members AND those who make comments???
No, they should not. Why else do you suppose you get all those spam registrations from Russian email addresses. I always wondered "why spam registrations?" but now I know, in case you have set the initial new member status to "contributor" or higher, then they can scrape all the active email addresses from the "comments" section. This is, in my opinion, a massive security hole, and one which needs plugging, or at least some advice as to how we can do this ourselves.
Which is what the original poster was asking for. So yes, your comment was entirely unhelpful.
I, too, would like a solution to this issue.
