Putting tape over your webcam is a great idea and EVERYONE should do it. Even the FBI director does it. If a hacker manages to get into your computer, it will be hell for you, but this is a super simple way to keep them from taking photos of you, especially naked ones that could later be used to embarrass, harass or blackmail you. (It won’t prevent them from stealing existing photos from your computer, however, so make sure you’re encrypting your naked selfies.)
