Sorry, I keep forgetting that spoilers can be rendered in different ways, based on a user setting. Apparently you forgot, too. ;-)
Anyway, of the five different ways of handling spoiler tags, only one requires the user to click on a link to retrieve the spoiler content. The other four options deliver the content with the page, thus affording no protection in the face of network content scanners.
So for spoilers to help in the way you suggest, all of the following conditions would have to hold:
So the user ends up clicking on the link and retrieving the spoiler content anyway. No protection.
