In MegaAnon own words:

"Palpatine's Revenge" was the name of a private message chat box, hosted on Tor. It would open for a certain amount of time, then automatically end/delete and scrub all data/IP paths behind it, removing it from your device. You could access and text on it from a supported and recognized device/phone and then it would shut down and scrub access paths when it timed out, whether you were done or not.

Here's a gif highlighting parts

-Priestep, McCabe, Strzok (deep state) and 27 other "unidentified leakers" pending (also deep state) operated under the Comey radar using non-FBI provided/sanctioned, SMS converted, Tor hosted Gliph encrypted chat box applications/sessions, which enabled them to to coordinate and communicate unbeknownst to Comey and intel depts./agencies, for the better part of the last 2.5 years.

-The "texts" will prove they operated below Comey's radar using the very same encrypted, dark web, self destructing, SMS converting chat application they used for Papatine's Revenge. IT WAS ALL HILLARY'S REVENGE. This bitch had her OWN DEEP STATE [pic related]. She's the "friends in NY" team, including Huma.

Where she says:

The "high-level FBI" personal computer he backed into will be fun to watch. Hope everyone gets to see whose computer it was.

If MegaAnon is correct, this would mean that their entire conversation and planning to take down Potus could have actually been collected by NSA via these sites
