You've bought a secondhand computer from an auction site. Unsurprisingly, it's not been wiped - most people are rubbish at wiping their hard drives. You're intrigued, though, and you discover some pictures and emails that haven't been deleted.
Oh my. Some pictures of a celebrity who you've heard of (and happen to like, though only on reputation; you've never met). Very intimate pictures. And they're with someone who isn't their spouse. The emails, which are similarly intimate, aren't to their spouse either. You've not seen anything about these two on the news, and a web search doesn't suggest anyone has written about their relationship.
You realise that these pictures might be worth something - perhaps quite a lot - if you sold them to a paper or website. Or you could wipe them. Or...
What do you do?
