Simple no configuration Genius.it annotator blocker.
This snippet on any web page (or in a .js file) will redirect away from genius.it back to the source site:
/* No Config genius.it blocker */
(function(){
var l = document.location;
if( l.host == 'genius.it' ){
var p = l.pathname.substring(1).split('/');
if( parseInt( p[0] ).toString() == p[0] ) {
p.shift(); /* Get rid Genius ID (if applicable) */
}
document.location = '//'+p.join('/');
}
})();
To block (or harrass) genius web annotators using an extension, use one of the other js files.
