As the saying goes： The Internet is forever.Once you've put something online-a credit card number，a silly photo，a heat-of-the-moment comment on social media-it an come back to disturb you.
   But what are the risks，rally？ "There are two worst-case situations，" says Richard Klosowski，privacy and security editor of a product-recommendation service. "The most obvious one is a security issue.Everyone's e-mail address and basic details are let out somewhere online，and if you reuse passwords，that means a criminal or immoral person will have an easier time getting into your accounts."
   The problem is getting worse：Identity theft cases more than doubled in 2020，according to a survey conducted by Harvard university，with reported financial losses from fraud （欺詐） overall climbing to ﹩3.3 billion from﹩1.8 billion in 2019.
   "The second worst-case situation is more primal：embarrassment， "says Klosowski.And sometimes the pricks（刺痛）to our pride are far more personal than feeling ashamed over an awful photo. "Many of us store our most intimate thoughts in a digital notes app，draft e-mails we never send，or pour out our private feelings into a direct message to a friend.This is the type of thing that can be disclosed online，either through a provider being ignored or through your own misunderstanding of the often-confusing privacy settings in the software and services. "
   With these sorts of slip-ups，the stakes can be high，But you're not powerless.You can stand up for your privacy and begin to take control，starting right now.
