I agree that it must be possible to identify people who hold resources. Not just for other network operators but also so that organizations such as law enforcement are able to do so in emergency situations where contacting RIPE could be too slow.
It is worth noting however that there now is a relatively large number of people operating networks as a hobby outside of any business activity.
At RIPE 84 I mentioned the possibility of publishing a name and city only and having RIPE hold the full address. This would likely be enough to unique identify a person (or at least a small number of potential people in a single city that would be few
enough for law enforcement to all check out) while not publishing the full addresses of people who could be at risk for various reasons. It would also be enough information to identify multiple objects belonging to the same person, for example to block traffic
from all of their networks. The full address could still be obtained from RIPE with a court order if required.
