I wanted to revisit this topic because the situation is becoming persistent. The warning appears in my account each day, and there is always a new entry in the unathorized list. They are, for the most part, various Google/Bing/Yahoo extensions. But rather obscure search engines are now appearing as well.
I had hoped after ASA's advice, that this would be a temporary concern. It isn't.
