I was thinking about a product like this marketed at new parents. A lot of people like to post pictures of their kids but I can imagine situations where removing these pictures some time in the future would be really beneficial.

Imagine you post a bunch cute pictures of little Jonny as a toddler. Maybe when little Jonny is in high school he doesn't want classmates to be able to find every "cute" picture of him that his mom wanted to share with her friends and family. Obviously once those pictures are "out there" they're potentially out there, but something like this could help, especially for situations years later.
