If your social media account has been hacked, there are several steps you should take to ensure your account security and privacy:

1. Change your password immediately and make sure it is secure and complex with a mix of uppercase and lowercase letters, numbers, and special characters.
2. Enable two-factor authentication which can help protect the account if your password is compromised.
3. Check your recent activity to make sure nothing has been changed or accessed without your permission.
4. Notify your contacts. Let your contact know if you've been hacked, as they may have received suspicious messages or posts from you.
5. Update your security settings and privacy settings. Make sure to review the platform's Terms and Conditions on privacy and security.
6. Review all posts. If anything inappropriate has been posted on your account, delete it.
