One issue I'd like to report that I haven't seen mentioned is that comments (both ones you've made and replies) don't show up if the comments are on images with blacklisted tags. There is a way to view them, by clicking said blacklisted tags at the top of the screen. However, that also shows the image itself rather than the "Blacklisted" thumbnail.
Even stranger is that, for comment replies, if the user has a blacklisted avatar, that still shows up as the "Blacklisted" thumbnail.
