They will still ask him to invert a binary tree, just to be sure he can code

Here’s a crazy idea. What if down voting a comment/post resulted in a weighted random float between 0-1 while upvoting resulted in a weighted random float between 1-2? If you virulently hate a comment or post, ignoring it is the surest way to bury in completely. Posts and comments that Garner attention become the most visible, but gaming the system for visibility could become difficult if the weighting algorithm was tuned appropriately.

You could create an ED25519 keypair, then with each post, produce a sha256 hash of the post, create a signature of the hash using your private signing key, then include the signature with the post. Anyone could easily verify the signature with the verify key. You could add the verify key to a personal site or something.
