Well, that assumes the template loads before the page.

Actually, as a Wiki, is it our duty to be so concerned in keeping spoilers hidden? Take for instance, Bluefire's opposition to Forum:Spoiler Images. Most large-scale Wikis and Wikis alike have a warning on their front page about spoilers and maybe just a warning banner on each page with a particular spoiler. We've already done most users a favour by putting spoilers in a collapsible box.

And if anything, I think it's common sense that if someone is to browse a Wiki page about a game or movie, for instance, there will be spoilers. I guess I would assume that is why most Wikis don't go through all the trouble of covering spoilers up with a huge banner.
