Asking this on behalf of a friend, my friend is about to start his teacher training to become a secondary school teacher. He uses Grindr and is wondering whether it would best to delete it due to becoming a teacher as he doesn't know if there are polices that discourages use of using apps like Grindr in case of coming across underage kids which I'm sure there are on Grindr like any other dating app. Is my friend overthinking things or is he right in being concerned?
