Network Solutions has pulled the plug on a promotional website for a film made by extreme-right wing Dutch politician Geert Wilders.
Wilders film is expected to very critical of Islam - last year he called for the Koran, which he compares to Mein Kampf, to be banned.
Network Solutions said it had taken action because it received complaints that the website breached its terms and conditions and Wilders refusal to discuss the matter with them. The company said it acted in response to Wilders public comments for planned content for the site.
The company said: "If the customer provides Network Solutions with the content and it is determined that the content does not violate the Acceptable Use Policy, then the customer will be permitted to post the content. However, if it does violate our policy, then the customer is free to post the content using another number of other avenues, but not with Network Solutions."
It said it did not proactively police content unless a complaint is received.
