My thread disappeared from the subreddit's list

https://m.reddit.com/r/yugioh/comments/4erf0q/this_guy_is_selling_deck_lists_on_ebay_for_20/

Posted a thread here, and it was receiving a lot of positive attention for a while. But at one point, the comments stopped. I checked, and it isn't showing up in the subreddit's timeline. Any ideas?
