Right, and there's no possibility to do research/testing anonymously anyway.
You use your personal e-Signature/ID card to logon to government sites, your logon is always tied to you.
Many different hops will log things like HTTP paths, which include GET information - or DB audit logging which can easily be traced with message ID's or timestamp comparisons. It's surprising how easy it is to trace issues, debug logging is often left on in Production systems..
I wouldn't take that risk.
