Streisand wanted to suppress photographs taken of her house. The photographer only wanted to take photos of the California coastline, but Streisand's legal action brought so much attention that people on the internet went to the site to see what she wanted to hide.What is that?!!?
Beyonce did the same thing when she tried (and I think succeeded) in getting unattractive photos of her singing on stage from being published. (We all saw the weird faces Bey makes while singing, but I think the photos are hard to find now.)
Anyway, it's when trying to suppress information backfires.
