Most people don't know about Innovis, which was mentioned in the article. That said, I've never run into a company where I've needed to lift an Innovis freeze. Anyway, I agree that it's tiring to constantly track which data brokers allow (are required to) adding a security freeze. In my opinion, better legislation is needed to curb this activity and data brokers in general.
