What I found when typing in part of my email address was bizarrely disturbing:
On this page is a review by "E. Taylor "elizabeth_jane_taylor" (24 September 2011)". And it is indeed a review I wrote. But I didn't write it on 24 September 2011 and I didn't write it on that website. It was written on amazon.co.uk years ago, just after The Da Vinci Code was first released on DVD.
Not that I really mind my words being spread around, but it was strange to see it re-published without my permission. Really random, too. Having glanced at the other reviews on the page, I can only think that the website owners were looking for reviews that compared to the book to the film. Maybe it's a new site and they wanted to make themselves look popular by stealing reviews from elsewhere and claiming users wrote them on their pages.
It's still rather disconcerting. And shows how things don't simply disappear from the web once you publish them. They can, apparently, randomly reappear after years of being forgotten.
Be careful what you write: you never know who might be reading or where it's been published.
