I would be bound to think it is a glitch. I actually forgot that I had a login at work that another employee had used while he was here, until I checked my work email and I got the "6" reminding me of my password. Checked my regular email to and got the 6 for this one as well. Was kind of worried for a moment, but if everyone else is getting them, I guess I won't fret. Can't really imagine someone trying everyones logon 6 times, especially the ones that aren't in use and they haven't seen for over a year and a half.
