Thousands of celebrities' names – including Angelina Jolie – have been blocked from new adult web domain .xxx.

The .xxx suffix, which launches in December, is being introduced to make it easier for web-surfers to find or avoid pornographic material online. It has been dubbed the 'online red light district'.

Adult entertainment websites can already apply for web domains using the new .xxx suffix.

However, the recent wave of blocking means that 'cybersquatters' will not be able to hijack celebrity names to drive traffic to their sites.

AngelinaJolie.xxx and BradPitt.xxx are among the names that have been blocked.

The company managing the new domain, ICM Registry, said it had already reserved 15,000 names as requested by child protection agencies and governments, including underage sex terms and the likes of David Cameron and Margaret Thatcher.

ICM's chief executive Stuart Lawley said: "The reason we banned the celebrities' names was because it's very difficult for them to trademark their names. We didn't want to have the embarrassment of AngelinaJolie.xxx coming up at the launch of the new domain."

Around 1500 domains have already been allocated to 35 porn companies. Lawley added: "We hope to sell 500,000 domain names by January/February."

It is hoped the new domain name will heighten security barriers and prevent children from stumbling upon sexually explicit content online.
