    Depends on the kind of blur. Some kinds can indeed be almost perfectly removed if you know the used blurring function, others are destructive. But, yes, don’t take that chance. Always delete/paint over sensitive information.

    Source: we had to do just that in a course I took a long time ago.

      I prefer sampling the surroundings, typing out a different number or text over it, then blurring with a non destructive effect.

      wouldn’t you also need to know in what kind of pattern the blur was applied. I am sure if you do it multiple times starting from multiple non identical partitioning of the region, it will be impossible.

      Always paint over sensitive information.

      Not in PDF tho. There, the stroke is saved in metadata…
