Forum:Should we warn about spoilers?

When writing an article where should we put the Spoiler alert in the middle of an article e.e. the Sasuke page has the warning at the top of the page but not all of the writing is spoilers, so should we have more than one spoiler alert for each article to show were the spoilers start and end and if theire ar more spoilers in the article have another spoiler alert start and end at the start and end of those spoilers.
