The post, about Lisa Page's congressional testimony, was shown as an active post when Davis looked at it on his account, but the URL actually displayed the same way as a deleted tweet for other users — essentially making it invisible to the public.

"Is @Twitter experimenting with shadow bans by deleting tweets so others can't see them, but keeping them visible to you while you're logged in? I had to re-publish my original Lisa Page transcript tweet because it was disappeared to everyone but me," complained Davis on Twitter last Tuesday.

Then, on Monday, Davis published a follow-up post containing an email Twitter had sent to him which he says admits that the post had been shadowbanned.

"Our priority is to keep people safe on Twitter. As part of that work, we err on the side of protecting people and sometimes mistakenly remove content that doesn't break our rules," claimed Twitter. "When those mistakes happen, we work quickly to fix them. We have corrected the issue."
