Polite version

wetwareproblem:

tumblr is silently shadowbanning posts based on unknown criteria (unlikely to be image-matching, we suspect text content). Affected posts appear on dash and dash-like views, but not on the actual blog page as seen by other users. I have been able to see the effect personally on desktop. Almost certainly related to the gutting of the chronic pain tag and similar hits previously.

There is no red warning bar and no way to dispute a shadowban.
