So I tried unblocking everything, and the comments appeared, even while logged in. I then re-blocked the users and it was still fine. I then re-blocked lemmynsfw.com and the comments disappeared. I tried the other domain I have blocked, and it did the same thing. I finally tried a third domain that had not previously been blocked, and it happened again. It seems like the comments disappear if I block any instance at all.
EDIT: I also confirmed that none of the commenters were from the blocked domains.
