How to block Facebook message to my phone?

I made a fake Facebook for these mobile games I play and I haven't friended anybody or accepted any friend request. But every day I always am receiving a text from Facebook Asking me if I know a person I know and I have over 99 notifications! So I've tried blocking the messages sent by saying do not disturb. I'm on iPhone. Then I delete the conversation then 24 hours later I get the same except message please how do I block this stupid stuff thanks!

Turn off Mobile Notifications to do that on Facebook go to Settings then go to Notifications Under Mobile Uncheck anything you do not want to get Texted about save the changes and you should be all set
