#but i emailed support and they did fix it after some time
no, seriously, you are not shadowbanned
if you were shadowbanned you wouldn’t be able to tell that your posts weren’t showing up in tags/searches for everyone else because a “shadowban” specifically refers to a state in which you can’t see that you are being removed from everyone else’s searches & feeds.
either the post was filtered from searches by a robot or your blog isn’t indexed. a search ban is not a shadowban. having “hide [blog] from search results” enabled in your blog settings is not a shadowban. not even being marked as spam is a shadowban.
tumblr has no mechanism for fooling you that everything is normal when it’s not, it just doesn’t tell you why your post isn’t searchable.
