I noticed that you have been adding the spoiler template to a large number of pages recently, however, the template itself is amongst a select few that are no longer in use. Therefore we, the staff, would appreciate if you no longer used it even though it isn't stated anywhere which is our own fault, obviously.
Well, at some point it was decided that a spoiler template would be obsolete since we aim to be as informative as possible. A brief spoiler "alert" has been implemented on the home page, however, it could easily be more visible than is the case. The decision was made before I joined the staff so I can't tell you much more than that to be honest.
