If I may, that Christophe name is likely to be an alias, as we found out earlier.
Also the "Kurt Larsson" name arrived in the mix because of a reverse lookup on the telephone number which was included in the DNS record, but actually this too is very likely to be fabricated, and the persons who, in the real world, bear these names (one "Christophe" is a completely unrelated dutch citizen, while Mr. K. Larsson is an aged 72 years old person who happens to be living in Lulea) have had their share of annoyance because of these false clues.

There is a very serious piece of data that may constitute a solid starting point, if put in relation with other elements of information gathered elsewhere : find detailed information about the company which was hosting the website. In order not to influence you, I won't tell more about this for now, but if you manage to find which company (which might be part of a larger group, so prepare to go deep in the level of details, and do not stop at the highest level), and the details of how they make business, that would be quite helpful.
