Discovered a mysterious Reddit account, /u/A858DE45F56D9BC9.  Similar to, Webdriver Torso, if you like mystery accounts and puzzles.  The account has a 4 year badge on Reddit so it’s not new news but it’s new to me and perhaps you as well.  A related post describing decoding one of A858’s posts with a base64 decoder along with transposing a few letters yields an ASCII image of Stonehenge.

Incidentally, the latest ciphers are not simple base64 transpositions.  If you have successfully deciphered them, feel free to post your examplescripts in the comments or leave a link to your site.
