It would be very easy to spoof those values in a handshake though, unless you’re proposing that in the initial data exchange a remote server gets a dump of every post and computationally verifies compliance.
Federated trust is an unsolved problem in computer science because of how complex of a problem it is.
Spoofing that handshake would be a bad faith action, one that would not go unnoticed longer term. Instances with a bunch of bad faith actions will make the case for not federating with themselves.

It just has to go unnoticed long enough to spam for a few days, get defederated, delete itself, start over
