If the rules were Animal Crossing Bells more clear (ie: spoiler tags necessary for events that have not happened in real time or spoiler tags required for articles that contain items which have been attained via hacking to bypass timelocking) possibly users wouldn't accept it as a personal assault on their play style when people requested they use a spoiler tag.
Rather than feeling sensitive about a sensed conclusion about time traveling it could only be a simple"hello that is against the rules, see sidebar".
(Edit: it is fine to downvote that if you're a avid TTer and don't want to indicate spoilers or something. Just trying to offer another viewpoint in this thread that is asking for comments )
The things which make my Reddit feed and also top the list on sexy following the sticky are varied on topic so I would not say there is an issue with common occurrences that community upvoting and downvoting doesn't already solve.
I usually think spoiler tags are somewhat silly, but you would need to go further than simply time travel if you really wished to prevent spoiling things people have not seen yet. All out of present season content would require a tag weather it's an old image from the image library or even a new image from time traveling both will reveal new gamers thing they haven't already seen. Plus things like the latest direct video clips would need tagging because it shows new Cheap Nook Miles Ticket content before anybody gets an opportunity to view it in-game.
