From the console log:
Blocked http://kkkkkkkkkk63ava6.onion/blog/ in page http://kkkkkkkkkk63ava6.onion/blog/ from extracting canvas data. http://kkkkkkkkkk63ava6.onion/blog/:51.
Line 51 is related to Wordpress' emoji-rendering code, which is done with the HTML5 canvas.

Following the advice outlined on, this prompt no longer appears.

Of course, we no longer have the Wordpress emojis, but that may be a good thing depending on how you feel about them :)
