Related bugs: bug 353648, bug 418177, bug 621085, bug 616587, bug 768095 (probably a duplicate of all of the above). As you can see, plenty of issues that have still not been tackled :(
I'd say the gist of this bug is a duplicate of 353648, but it describes other problems (namely emailing people it shouldn't) that should be fixed.
