When an offending notification pops up, simply long press on it and App info will pop up. Tap on that and you’ll be taken straight to the app management screen where you can uncheck the Show notifications box and free yourself from spam. It does mean that all notifications from that app will be turned off. As the warning states “If you turn off notifications for this app, you may miss important alerts and updates.”
You can also go to Settings > Apps and slide over the All tab and run through each app, unchecking that Show notifications box for anything you don’t want bothering you.
