If you head to the website and put your name and DOB, the cancellation of your ballot after requesting a replacement is mentioned at the bottom of the page

I'll add that anyone can request a replacement, and the cancellation is effective immediately

If I had to pit 4chan against HN in a scavenger hunt, I would bet on 4chan.

edit: in fact I think this happened. wasnt there an online quiz we lost at a couple years ago?
