Also how the fuck are people figuring out what is underneath attempts at blurring or blocking out the image? This seems a bit far fetched that people can reverse attempts to cover sensitive information on an image.

Sharpening techniques, especially combined with machine learning processing can de-blur things, also pixelated blurs have been undone if not too extreme. The best is fully opaque black instead of manipulating the imagery, as manipulations may be reversed.

Some people use the “marker” tool to censor photos because the brush is larger or it’s the default tool. But most marker tools have some transparency to give realistic looking strokes. It’s possible to draw over the image to the point that it looks visually hidden, but if the underlying text is even slightly darker it’s possible to reveal it on a computer.

So always use black, duly noted. Thank you!

Solid black boxes. Never the black marker or highlighter tool. Never blur either since those can sometimes be reversed.

Takes like 30 seconds to uncensor those photos.
