I tried Bing and Yandex to find the email bodies. They didn't return many results (but they do return results).

When I try on Google to find the email bodies, I get 250k results, of which the large majority are on blogspot.com sites.

While mail bodies can be found on a few other sites, like the asdasd.ru example, and other search engines have found these links too, the main issue still seems to be with blogspot.com -- These aren't throwaway accounts with public inboxes, but likely some virus that is intercepting certain mails (Facebook, Twitter, Youtube, Twoo) and reposting them as a blogpost for everyone to see.

As Blogspot is Google-owned, this does seem to me a predominantly Google-specific issue.

No, Blogger also has a feature that will automatically post messages sent to an email address. Here's an example email from Facebook that was posted to a blogspot.com url: http://weight-loss-information-123.blogspot.com/2012/08/misb...

If you look at the bottom of that Blogger post, it says "This message was sent to <a gmail address>." So an email from Facebook got posted as a web page to this blog.

There's no need to suspect some virus that's intercepting emails. Plenty of people have set up their systems such that email messages get turned into web pages.

You are probably right and I apologize for any misinformation. To me it seemed strange that the blogs first started spamming, followed by publishing only certain emails. Wouldn't it make more sense if all emails were published, not only from certain webservices? Why would a user want to publish their private Facebook emails in the first place? None of these accounts posts normal updates, they act compromised.
