Every time you open your social media profile, you share information with the world, as this is accepted when you create an account. This is extremely dangerous because networks like Facebook use their own information to provide them to companies that seek to influence their opinion about who to vote or what products to show to sell. In addition to sharing this information, we are exposed and anyone with any disorder can use it to harm us or even hackers who want to access our bank accounts.
For this reason, it is recommended not to share sensitive personal information, not share our location and not accept friend requests from strangers.
