I am getting people added to our database from Contact Source called Get Updates. I don't know what that is.
Friendship Circle, Welcome to SE.
There are many ways the contact may have contact source.
- Contacts being created from import with contact source.
- Webform/Caldera for submissions with contact source set as default and hidden
- Schedule job that pulls contact from external source and add's into CiviCRM like google contact sync, mailchimp sync etc
- Contribute/Custom modules/plugin that is responsible to add contacts from a form like newsletter signup etc
