Many blog readers are expected to post comments - and to leave their email addresses, as part of their message or profile, to allow direct contact. Long ago, I used the email address of my commenters, as part of an easy "Contact Me" form, on this blog.
Recently, we've been noting that Blogger comments don't always include a useful email addresses - many comments simply describe the commenter as
firstname.lastname@example.orgNot all blog owners - and readers - appreciate this change.
When I leave a comment using my google profile, it isn't linking my profile with my email address. How do I get my email address properly displayed?and
Why do so many comments, published to my blog, show the email address of "email@example.com"? How do I email my readers?
For some time, we've known of the dangers of revealing your email address to the world, in general.
Blogger blog owners have been a known special risk, with their email addresses. Google developed Google+, with the Google+ profile, to allow everybody to network with their friends - both old and new - without the risk of revealing one's email address.
Google+ replaces email completely. You can share comments, messages, photos, and videos with anybody, in a self contained universe - and you can define your own, personal universes. This leaves the need to reveal your email address completely unnecessary (though you can use email, if you wish, without knowing anyone's address - or revealing yours).
After Google+ became popular, Blogger added the option to link our Blogger blogs with our Google+ profiles. Blogger profiles, based on Google+, are cleaner, and use the Google+ displays to update.
To encourage people to use Google+ for peer to peer networking activity, and to make our Blogger accounts and blogs safer, Blogger has eliminated our email addresses from all outside correspondence - including when we publish comments on Blogger (and non Blogger) blogs, using a Google+ based Blogger profile.
If we publish a comment on somebody's blog, and the blog owner has enabled comment moderation or notification, our comment shows up in the email inbox of the blog owner - but with our email address displayed as "firstname.lastname@example.org".
With email addresses not displayed, this helps protect our Blogger account names from becoming unnecessarily revealed. Blog owner - reader comment communication is still possible - but again, without the email address of the reader being known.
Some time ago, I discovered an odd type of comment spam, which I termed "nice Blog" spam.
Nice blog. I will keep visiting this blog very often.This spam, from what I can tell, has been published by the millions, in various blog comments. It's likely that this particular spam is being published as a very imaginative form of email address mining, and recently became even more imaginatively produced.
All that the spammer has to do is publish a spam comment, and select the option to "Send me replies". Any comments published later, and including the commenters actual email address, would be delivered directly to the spammers inbox. Knowing the email address - and the blog URL (how many comments do not include a link to a blog?) - the hacker would go straight to work.
Later, we would see forum reports.
I can't control my blog, any more - and somebody has updated it with spam!This was a direct result of the former blog owner, having left a comment on somebody else's blog.
By eliminating our email addresses from our comments, Google is helping to protect our accounts and blogs, while letting us continue to comment on each others blogs - and to eliminate one type of unnecessary spam from our blogs.
Google+, which replaces email for networking, uses a "Friend of a Friend" relationship to let you expand your universe infinitely, with each comment, message, photo, and video that you share. It lets you control the expansion of your universe - if you wish. And, it helps keeps your Blogger blog under your control.
