Answer 1

My simple way, but it can help for further variations on this subject. List all methods and alter them to useless.

  Object.getOwnPropertyNames(console).filter(function(property) {
     return typeof console[property] == 'function';
  }).forEach(function (verb) {
     console[verb] =function(){return 'Sorry, for security reasons...';};
  });
