Re: lots of people pay for privacy service for whois info
That is how it works already in the EU. If you serve the name provider with an EU based warrant, they have to hand over the registration information for the named domain(s). That has always been the case under EU data protection law.
You can pass on the PII (personally identifiable information) with either a) the written permission of the identifiable persons in the data or b) a valid EU warrant.
So, basically, if the judge thinks the case has merit, you can gain access to the information, if he thinks it has no merit or is a fishing expedition, he will refuse the warrant and you don't get the information. A fair way to do business, IMHO.
