Social media age restrictions are restrictions on how old you have to be to set up a social media account. This age is usually 13 across most social media sites. But, restrictions can vary depending on the platform and the country. There are also age restrictions for certain content, such as violence and nudity, that requires ages of 18 plus. This is to prevent those under age from accessing this type of content. It's important to note that these age restrictions are set by the social media platforms themselves, and it is ultimately the responsibility of parents and guardians to ensure that their children are using social media platforms safely and appropriately.
