Need help with a query to identify the user who created saved search in Opportunity Marketplace and marked it as system default.

An employee has created a saved search and checked 'Mark as system default' that resulted it to be a defaulted filter for all employees who have not set up saved search in their logins. How do we identify the user who created this system default search and inform them to remove it as a system default?
