If one is working within their own personal account looking for certain emails, it would be somewhat hard to not enter personal information if looking for emails that concerned their real identity.

In the past it would have not been an issue for myself since I was and am careful not to include anything real for web based email systems. The only real privacy issue I had with yahoo is when they were tasked to nab my real identity back in 2004 or so, yup first time I forgot to use the second proxy (paid) ... obviously the web based proxy was not as anonymous as they claimed. P.S. nothing bad like cp -- just helping out by tracking down old hard to find drivers and such for those folks (by way of a forum) who'd lost their Dos / Win 95 based software or driver disk.

Now I'm left to wonder, by data does that just mean what one has as far as emails, attachments and various content that has been uploaded or all data including what yahoo has on the account holder which is not necessarily listed.
