It means surfacage doesn’t show up in searches.
You won’t be able to see that blog’s posts from the notification link if you are subscribed, or if you go on surfacage.net directly. The last post is the Willow ask from a earlier this week.
Essentially you would only be able to see posts if you scroll through your dashboard and somehow catch my post. There’s a good chance a lot of people won’t be able to see this post even.
It’s called a shadow ban because you won’t have any idea your posts don’t show up unless you check directly or people message you.
I’ll be messaging staff and see if this is a bug or something. I hope it’s just a bug.
There’s a fix for this, it’s annoying but worked for me – go to settings, click on the blog you want to make visible again, and activate “hide username.tumblr.com” down at the bottom. It makes your blog show up in dash by default instead of as a separate page, but new posts show up at least.
I couldn’t see new posts on my blog outside tumblr either. I did the hide thing as well and can see my blog in the dash as well.
