We can prevent it by not believing or sharing such stories without verification. Also, if we see them, we should report to the relevant platforms.
One way is through education. People need to be taught about the importance of respecting others and the harm that false stories can cause. Social media platforms also have a role to play. They can enforce stricter rules on the type of content allowed. Additionally, individuals should be more vigilant and not be easily influenced by salacious headlines or unsubstantiated rumors. When in doubt, don't spread it.
To prevent the spread of 'fake sex story', first, raise public awareness about the negative impacts of such false information. Second, media and social platforms should have strict fact - checking mechanisms in place. Third, encourage people to think critically. Don't just accept any story at face value. If a story seems too outlandish or inappropriate, chances are it might be false. By taking these steps, we can reduce the spread of such unethical and false content.
