I think it is not fake or dangerous, but he is a very busy collector.
His name and that of his wife is in the telephone register of Stockholm.
His photo's and text can also be found on websites like merchant-navy.net, flickr-tanker-groups, the Dutch website Kombuispraat and the tanker-website of Auke Visser.
Swedish people find the family very important and his wife seems to share his interest.
But I think he does not realize that the members of the website have already "emptied" their collection on this website so there is not much new to find for him.
And maybe he is not yet familiar with the button "save this image as" :-))
