What is a real life example of the Streisand Effect?

There are a bunch of examples (many of them dating to before the term) involving censorship.

Now, if you were trying to sell low-budget movies based on horror, gore, and sexual content, could you come up with a better advertising phrase than “video nasties"? Whitehouse and her compatriots not only made the public aware of these films, and railed about how terribly sexy, frightening, filthy, and shocking they were, but also kindly compiled a list.

These were very much underground, sold mainly by word-of-mouth and ads in specialty magazines and such, but most people had never heard of them. But they came to the attention of famed conservative activists Mary Whitehouse, who led a campaign to have anyone selling these films prosecuted. To that end, they compiled a list (initially of around 70 films, later expanded), which were dubbed the “video nasties”.

How do people move on so quickly? I’m still sprung over someone I was dating and he found someone else so fast. I feel hurt because I’m still head over heels over him while he’s out enjoying his life with someone new

Naturally, this campaign became the best possible promotion for films that many people would otherwise never have heard of.

One of my favorites came from Britain in the 1980s. There was a whole subgenre of low-budget exploitation and horror films distributed by videocassette, which bypassed the normal channels for rating and classifying films in the UK due to a loophole.
