My "messages" function seems to be broken—whether purposely by Tumblr or not, I don't know, but I can neither send nor receive them. I contacted them about it days ago, but there has been no response. If you are looking to reach me, just use the ask and request that I reply privately. (That seems to still work, at least.)
I've also noticed that whether I am logged in or not, I can search for my specific hashtags, such as "in death" or "advent children" and not see any of my own posts come up, even when I filter it by latest. I just posted a chapter of In Death with that hashtag 14 hours ago but when you search that, the latest post is from April 4th, and not mine. (And I've posted more chapters than one since that date.) I've checked all of my settings, and nothing seems wrong. Perhaps I've been shadow banned for some mysterious reason, hm...?
