Ask HN: Has anyone solved R/4a5e1?

I found a puzzle last year on Reddit. The entire r/4a5e1 subreddit contains 16 posts, where the titles and bodies of each post contain clues. I was able to successfully decode some of the clues, but I'm stuck on where to go next. I was wondering if anyone had some insight for me.

I posted what I found to https://github.com/49pctber/4a5e1 as a Python notebook. If you figure anything out, please let me know!
