Rather than feeling sensitive about a sensed conclusion
I don't think spoiler tags need to Animal Crossing Bells be divisive. Right now it will become an issue since there are no definite rules about what is expected and acceptable from the sub.
If the rules were more clear (ie: spoiler tags necessary for events that haven't occurred in real time yet or spoiler tags necessary for posts that contain items that were attained via hacking to circumvent timelocking) possibly users wouldn't accept it as a personal attack in their play mode when individuals asked 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 contrary to the principles, see sidebar".
(Edit: it is fine to downvote this if you're a avid TTer and don't want to indicate spoilers or something. Just trying to offer another perspective in this thread that's asking for comments )
The things that make my own Reddit feed and Cheap Nook Miles Ticket also top the listing on hot following the sticky have been varied on topic so that I would not say there is an issue with shared occurrences that neighborhood upvoting and downvoting doesn't already resolve.
