The term "earlier post" refers to a previous message or entry that was published before another. It could be referring to something written on social media, such as Twitter or Facebook, where users often publish multiple posts in chronological order and an earlier post would therefore mean one that appeared before another in the timeline of the user's feed. In other contexts, it may refer to a previous blog entry, news article, or any other form of written content published at an earlier time than another piece of writing.
