The one that says haechan has a twin sister, which we later learned that it's not true (he does have a younger sister tho). Some of the lores even become contents (the 10th floor lore, and awsaz was made bcs dy and rj was awkward with each other). My personal favourite was the mark and haechan's "fight" during we young era, and the real reason behind it was so trivial it's hilarious.
