We hear that their efforts were successful, as relayed by the Coalition Against Trafficking in Women (CATW):
Congratulations to Gudrun Jonsdottir and the women of Stígamót in Iceland for their brilliant strategy and work in getting a major pornography event cancelled there. This event, called Snowgathering, was modeled on the sexpos that are taking place in many other countries. The event was organized by 150 of the major global pornography producers, distributors and webmasters.
Gudrun enlisted the city council, police, other organizations and the hotels to stop the event from being held in Reykjavik. The pornographers were enraged and even threatened, on some of their sites, to "do away" with her and her daughter who is on the city council and introduced the motion to prevent the event from happening.
