SharkLaser writes "Two of the largest porn companies on the internet, Manwin and Digital Playground, yesterday sued both ICANN and ICM Registry, which runs the .xxx TLD, over extorting defensive registrations with ICANN's blessing. 'The complaint focuses on ICM's recently concluded "sunrise" period, during which porn companies, for about $200, could apply to own a .xxx address matching their trademark or .com domain.' Schools also felt the same way, and had to reserve domains under their name so that no porn content could be put up on them. The .xxx TLD has also previously been subject to criticism by both religious groups and adult industry, but for different reasons. Religious groups believe the .xxx TLD legitimizes pornography, while the adult industry believes it could lead to censorship."
