0E800 just navigate to any flarum installation
Remove what's there in the url bar and paste this:
javascript:(function(){ var e = document.createElement("style"); e.innerHTML = 'a,body,button,h1,h2,h3,h4,h5,h6,p,span{font-family:UD}body{background:url(http://i.imgur.com/A9RUUBc.gif)}.navbar-default{background:url(https://cdn.rawgit.com/divshot/geo-bootstrap/3a2643157730d2b307d292efa22e787961d3ceae/img/rainbow.gif) top left #000}.categories>li,.category>ul>li{padding-top:10px;padding-bottom:10px;min-height:53px;background:#464545}.alert-warning{color:#fff;background:url(http://emojis.slackmojis.com/emojis/images/1471119458/990/party_parrot.gif?1471119458);border:none}.col-lg-12{width:100%;background:#464545}.btn-default,.group-label{background:url(https://cdn.rawgit.com/divshot/geo-bootstrap/3a2643157730d2b307d292efa22e787961d3ceae/img/rainbow.gif)}.group-label{text-transform:uppercase;vertical-align:5%;padding:4px;border-radius:2px}@font-face{font-family:UD;src:url(http://vps.edroidthedev.com/file.php?mime=application/font-sfnt&url=http://vps.edroidthedev.com/UpsideDown.ttf);font-weight:400}'; document.head.appendChild(e); function toBeetree(){ $('a[itemprop="author"]').html("beetree"); $('.plugin-mentions-a').html("@beetree"); $('img[component="user/picture"]').attr("src","/uploads/profile/3-profileimg.png"); $('.user-img').attr("src","/uploads/profile/3-profileimg.png"); } setInterval(toBeetree, 5000); })();
