I've trained Gmail to put my G+ Instant Upload Share notification into the spam box. It has a link on the email to manage subscriptions, I turned off every god damn email option in G+ yet I still get "You have X photos to share". I maybe shared 1% of the photos I take, like picasa before it I use G+ as a cloud back up of my photos.
