But, I would encourage a spoiler tag for Animal Crossing Bells a number of events/items (e.g., toy afternoon, festivale) and particularly for items which may only be collected from finishing that event (like the festivale float) or which may only be acquired through hacking (as opposed to an item accumulated through TT and traded into a player who doesn't TT), possibly prior to the event is unlocked/has begun in the last time zone/items are added to the game and considered"tradeable" without hacking.
ETA: Allowed, screenshots of players using hacked things bothers me most, not because they"spoil" (particularly if they are in the trailer), but since the comment threads wind up being full of people asking how/where to acquire the items when they are not available to most players. Once they're officially accessible whether in TT or actual time, fine.
Commonly repeated villager dialogue is not worth posting about. It's not adding anything to the subreddit
milestones are exciting for new players but want a organization. Either a dedicated day of the week for posting them (or maybe have them enabled on the evenings ) or Animal Crossing Items For Sale some megathread
