The fact that *renting* is at all possible suggests to me that the followin=
g situation *could* arise:

* A market of lessors arises.
* A surveillor creates multiple identities.
* Each fake identity rents separately from multiple lessors.
* Surveillor gets privacy data by paying out rent money to the lessor marke=
t.

In defiads, I and Tamas pretty much concluded that rental would happen inev=
itably.
One could say that defiads was a kind of fidelity bond system.
Our solution for defiads was to prioritize propagating advertisements (roug=
hly equivalent to the certificates in your system, I think) with larger bon=
ded values * min(bonded_time, 1 year).
However, do note that we did not intend defiads to be used for privacy-sens=
itive applications like JoinMarket/Teleport.
