9 ouf out of ten "notifications" from their iPhone app, the little number in red, are paid(I suppose) notifications. So I ended up uninstalling it some time ago.
Sort of like before I deleted my Twitter and Facebook accounts, they liked to "ping" me if I hadn't used their app in a day or two. "Someone posted something" or "someone tweeted something". Was it a message directed at me, or did it "tag"/include me? Had I participated in the discussion? Nope, they just wanted to make sure that I used their app and got trained properly so that I would end up checking the damn thing every minute.
