Detect pushState and replaceState

detect-history-state.js

var _wr = function(type) {
	var orig = history[type];
	return function() {
		var rv = orig.apply(this, arguments);
		var e = new Event(type);
		e.arguments = arguments;
		window.dispatchEvent(e);
		return rv;
	};
};
history.pushState = _wr('pushState');
history.replaceState = _wr('replaceState');



window.addEventListener('replaceState', function(e) {
	if ( location.href.match(/[&?]ref_=/) ) {
		console.warn('THOSE FUCKERS GAVE ME A ?_ref AGAIN!');
	}
});

Nice!
