Single domain in, WHOIS data out.

I have a copy of the correspondence from Bundesamt fuer Justiz.

The cops questioning me did. I was actually under investigation for a different thing related to this website, so my lawyer got them to confirm it was indeed possibly related. They then dropped that investigation immediately, after months of nothing being added to the file (which I also have). While holding a pretty substantial bit of my hardware hostage. Weird how police work can be expedited when charges are obviously based on police not understanding how the internet (and Paragraph 10 TMG) works and they need to get something done for BfJ. Or maybe they did understand, but didn't want to afford those protections to an individual without commercial interest.
Mind that this was about 10 years ago by now.
