Short and sweet today: When celebrities have their personal property and/or information posted online, that’s a “theft”, not a “leak.” A leak suggests that someone with legitimate access to the information, or someone in the employ of the person or persons with access, has released the information to the public. Theft is when someone breaks in and takes it. They’re different.
If someone hacks your home computer, takes your passwords and bank information, that haven’t “leaked” the information; they’ve stolen it. The same is true of credit card numbers, personal contacts, or, more to the point, photographs. These nude celebrity images flooding the web right now aren’t “scandalous leaks”, they’re stolen property. Please remember that if you feel like you’re not doing any harm by seeking them out.
