quote: You are mixing up information about two separate leaks. The one from patriootti.com is a bit older and didn't have anywhere near the 16000 people of this later one. One aide to an MP of Perussuomalaiset has resigned as a result of the Kansallinen Vastarinta neo-nazi group's leak. Finland's total population is currently around 5,4 million and there probably are not even 16000 people in all neo-nazi and similar organisations in the country.The leak with contact information and social security numbers of 16000 Finnish people is from some other database. The officials have stated it's probably from the databases of some educational facilities, but online it's been speculated that the source of the leak might be the Finnish Transport Safety Agency (TraFi).

The hack was motivated by an apparent desire to shame the Finnish government into improving data security.
quote: Neo-Nazis preach a philosophy of hatred towards people of non-Nordic races. The movement is quite popular in the Nordic countries, thanks in part to the influx of Muslim immigrants into the region in recent years.
