I recall a story of a pedophile being caught because they posted pictures using a radial warp on the face. It wasn’t too hard for enforcement to code a filter that undoes the radial warp, and instantly saw the original photo to identify and lock away the creep.

Based on the documentary linked by @alwaysconfused@lemmy.ca, at 9:50, it looks like the swirl effect was unique in being able to be undone, since it was neither “typical censor nor blur”.
For those who are interested, here is a 20 minute mini-documentary about this individual that goes by the name of Mr. Swirl.
Here is an alternative Piped link(s):

A warp doesn’t technically lose the information, it merely displaces it. A good blur algorithm on the other hand will lead to loss of information.
This would demonstrate it well with physical concepts
