I found this post on thedonald, and I think it's potentially interesting, especially because of the timing of the deplatforming right after this got out.

Here's the rundown:
Parley from Lin Wood gives Isaac Kappy's supposed deadman switch password
https://archive.fo/V14NK
“cultstate.com has issued protections on this matter”
The sha-512 checksum of that phrase is:
86d53c1315f42ea48caa0dc1b82a1c61e988b1035db897e90c2303c05d8721648ca816eada320c950b75985575b495a12c06d0a0ba77b9e23ccbd7d31b5bd035
Isaac Kappy's tweet from before he "committed suicide" had that same checksum.

The one potential wrinkle described on thedonald thread is the poem "I Ask Papacy" on the site cultstate.com
Could potentially be a "drink more ovaltine" moment by the owner of that site as discussed td, but seems like a strange and counterproductive move also, especially if he was a friend of Kappy.
there doesn't seem to be anything here
