So that you guys could do a memorial thread one day a week, a fashionista thread the following day a week, a'look what I got' day, and Nook Miles Ticket an edited screenshot day. Usually bots/auto-moderators can be installed to do this automatically if a mod doesn't want to do it themselves.

That way the most controversial posts: memorials, generic costume spam,'check out this villager/item I got', and edited screenshots are all relegated to their own space where people who wish to see them may, while the main subreddit focuses on other things. Maintaining the threads on a cycle and removing/posting/stickying new ones can ensure they stay clean and people continue to make use of them.

If folks are time-traveling to an event which hasn't released then yes there needs to be spoiler tags. The best instance of this was that the Halloween upgrade when people kept posting screenshots of the carriage they time traveled for. Like I'm alright with seeing someone post rabbit afternoon screenshots right now, because that event released last year so we already know what the items are. But if they include, IDK, an arbor day event with new things that people TT to, I would prefer if they spoiler mark their posts so that I can choose whether I wish to see the content or not.

It actually comes down to choice. Some folks do want to cheap Animal Crossing Bells find spoilers, others don't. As long as people can choose whether they wish to see it, I do not think there'll be any issues.
