Wordpress RSS Feed显示原始短代码（不渲染）

I'm using the default RSS feed to pass some content through to some subsites I manage. But there are some shortcodes which are being rendered, but should be rendered by the subsites.

So how do I prevent the shortcodes from being parsed?

The shortcode it's about is from a plugin.

[wb-rekentool "username/othername"]

I solved the problem! Used the "the_content_feed" filter to remove the shortcode:

function remove_sc_feed($content){
    remove_shortcode('wb-rekentool');
    return $content;
}
add_filter('the_content_feed', 'remove_sc_feed');

Easy, but the answer was nowhere to be found!
