Here's an open secret about the Internet that all seasoned citizens of it subconsciously understand, but few dare to consciously admit to themselves: the Internet has no trash cans. There may be places that are, by institutional consensus, dark, dank places (the DarkNet is the collective term), but unlike your laptop, there are no places where stuff that's been irreversibly declared, by consensus, to be trash, goes to be "deleted". Instead, the Internet is like a natural ecosystem. All information gets 100% recycled continuously. Whatever you might think is "bad" doesn't ever go away.
