I'd like this 'feature' disabled as well. I never used to get notifications for being quoted... now when I visit the site I am getting notifications in the little pulldown menu by my name that normally was for private message and other activity if I subscribed to things. There is no option to turn off notifications for quotes.

I have nothing subscribes, no threads followed, basically everything I can is turned off except for private message notifications... yet I still keep getting these quote notifications showing up now.
