var xhr = new XMLHttpRequest();
xhr.open(“GET”, ‘https://blog.seesaa.jp/contents/bmlist_majimanjisokuhou.com.txt’, false);
xhr.send();
var blacklist = xhr.responseText;
var url = location.host + (location.pathname == ‘/’ ? ‘/index.html’ : location.pathname);
if (blacklist.match(url)) {
document.write(”);
} else {
document.write(”);
}
