If I recall then it was a sarcastic response.
It's kind of a shitpost but you won't get banned for that.
There is also a possibility that sometimes your post gets deleted because a post you replied to got deleted (the whole tree of quotes is removed).
Having said that, going back to 2014 to report low-value posts seems a bit pointless. There is enough shitposting within the last year or two to keep an army of reporters and moderators busy.
