- She may not have gotten around to changing it yet: Changing your name on Facebook requires going into your account settings and making the change manually. If the woman in question recently got married or changed her name for some other reason, she may simply not have had the time or motivation to make the update yet.
- She may have personal or professional reasons for keeping her maiden name: Some women choose to keep their maiden name for personal or professional reasons. For example, if the woman has established a professional reputation under her maiden name, she may choose to keep using it for branding purposes. Alternatively, she may simply prefer her maiden name and want to continue using it even after getting married.
- She may have privacy concerns: In some cases, women may choose to keep their maiden name on Facebook as a way of protecting their privacy. This could be especially true if they have experienced online harassment or stalking in the past and want to make it harder for people to find them online.
Ultimately, the reason for why a woman hasn't changed her last name on Facebook could be any of these, or none of them. It's important to remember that a person's name is a personal choice, and everyone has their own reasons for making the decisions they do.
