Protect campaign data

Replace private domains, campaign names, account identifiers, keywords, and partner names with fictional values. Most parsing and normalization problems can be reproduced with example.com.

Before reporting an audit result

Check the current naming rules in the workbench. Unknown source and medium findings depend on your local allowlists, while case, duplicate-key, missing-field, and fragment findings come from the URL itself.
