I'm on Facebook to keep in touch with friends abroad and for family photos. I've tried turning everything off as I would prefer to be anonymous but unwanted Facebook 'Notifications' keep cropping up on my phone whenever I use it for internet - which is very seldom. These also appear on my laptop. I've never posted on the site and have tried turning off all Notifications without luck. Please do not recommend WhatsApp etc. as I'm a total luddite. Any ideas. Thanks
