I've noticed the same problem -- someone had flagged one of my packages OOD four or five days ago, but I only just noticed today after checking my packages on the web interface. My email is correct, and I am still receiving comment notifications on the packages I am subscribed to, I simply have no record of anyone flagging my package out-of-date.
I had assumed that I must've unknowingly misclicked at some point, and that you don't get notifications if you're the person who flags your own package. If other people have had the same problem, then perhaps there is a bug. Cheers, WorMzy
