A question

I made a post on reddit, which went viral amassing 70k views and 1k upvotes. However, at it's peak, it was taken down by the mods, and no reason was provided. I'm relatively new, and Don't understand why this happened? Can someone explain (also telling me more if possible?) Thanks in advance guys!

Edit: It happened in this very subreddit

Edit 2: (img below)

have a look here!!
