Facebook users still claiming to see private messages in their timelines

In my own experience, even with things as simple as logging into our site, I've had users file angry complaints and bug reports INSISTING that I deleted their account, because they KNOW they're using the right email, and they've tried every single password they've ever used and can't seem to get on the site. Ten minutes later I'll get another email saying "Nevermind, I forgot logged in with Facebook."
Point is, users frequently don't know what they're talking about.
A friend of mine, software developer as I am, hardly use Facebook because it doesn't like it. And when it does it is through _private_ messaging. And there, on my timeline was a private of his.
I joined in 2004 and remember how people always just wrote on each others walls myself (if you were an early user you probably also remember that people would have full conversations back to back on each others walls as you couldn't leave comments on wall posts). It's probably just a matter of people not recalling this was how Facebook used to behave.
I won't believe these rumors until I see examples of intimate exchanges – whether they be sexual or personal details one would surely not publish such as a bank card PIN or SSN.
