I think I'm having the same issue as well.
I'm getting a sitemap warning via google webmaster tools:
Sitemap contains urls which are blocked by robots.txt.
The offending URL is:
http://www.thesocialwhat.com/wp-includes/js/tinymce/plugins/wordpress/img/trans.gif
I've tried deactivating and deleting the plugin, and Google still claims the issue persists.
