Additionally seeing spoilers and Animal Crossing Bells time travel, I know think it's a remarkably difficult thing to moderate regarding seasonal events and items. I do however think that spoilers could be used for time locked items (such as the mario things ) which are hacked in prior to their release date. This would be taxing to medium since there's a fixed release date for the items along with the spoiler tag can be enforced in the afternoon of the upgrade to the day of item release. It's not something that bothers me personally but might be something to consider.
On common occurances I think that milestone posts are great for the subreddit entire as animal crossing is largely a game about setting your goals and I think it's great that people have a place to share them. I'm also very sympathetic about the tacky limit and with this in mind I feel that the present codes and queries threads do a nice job of maintaining the subreddit clean.
Anyhow that was my two cents, I think you guys do a fantastic job with the subreddit and you are taking it in a fantastic direction!
There should be more restriction on this. Literally so many posts of"Margie Wearing Glasses CuTe! 1" or "AnKhA on The Beach wow!" Like they're not even pointing out anything special or unique with Animal Crossing Items For Sale the game.
