Decrypting the strange subreddit /r/A858DE45F56D9BC9.

Hints

• /u/fragglet deployed a scraper and auto-analyzer for postshere: soulsphere.org. It is on github
• the format changed at some point. old format vs new format
• each post is of various length and some may be cut off
• it appears to be hex encoded data that probably breaks down into binary
• it does not directly convert from hex to ASCII
• sometimes when broken down into binary, the number of bits does not evenly divide by 8. It does divide by 4.

Community

• there is a subreddit devoted to solving this.
• there is a wiki on it
