I may be misunderstanding your instructions, but I think the intended use (in Chrome, at least) is to highlight the javascript and drag it to your bookmarks bar. This creates a bookmark that executes the javascript, which you can click to unblock the WSJ article you're currently viewing by redirecting the current page through Facebook.
Another useful bookmarklet for deleting annoying DOM elements:
javascript:(function(){document.styleSheets[0].addRule(".highlighted_to_remove","background:red !important");var e=function(e){if(e.keyCode==27){i()}};document.addEventListener("keydown",e);var t=function(e){e.stopPropagation();this.classList.add("highlighted_to_remove");return false};var n=function(e){e.stopPropagation();this.classList.remove("highlighted_to_remove");return false};var r=function(e){this.parentNode.removeChild(this);i();e.preventDefault();e.stopPropagation();return false};var i=function(){var i=0;var s=document;while(s=document.body.getElementsByTagName("*").item(i++)){s.removeEventListener("mouseover",t);s.removeEventListener("mouseout",n);s.removeEventListener("click",r);s.classList.remove("highlighted_to_remove")}document.removeEventListener("keydown",e)};var s=0;var o=document;while(o=document.body.getElementsByTagName("*").item(s++)){o.addEventListener("mouseover",t);o.addEventListener("mouseout",n);o.addEventListener("click",r)}})()
