Wish I had the technical knowhow to help with this, anon.
On another note, one thing I never liked about halfchan is the vanity of the posters with info. If this was on qresearch it would've been laid out with screenshots and documents, without the fun riddle air to it (still glad you shared it though, it's intriguing).
Nice digs, anon. I can't seem to locate anywhere in the indictments list where an mx is listed.

Digging now. Not sure if we'll find the MX link here but who knows.
God Bless, SwordAnon.
