An educational Web site run by Ernst & Young has been replaced by a XXX porn site featuring "165,000 Barely Legal Teen Movies", the global professional services company admitted yesterday.

Its popular Moneyopolis game site - which is designed to improve numeracy and financial skills of students - has been available at moneyopolis.com and moneyopolis.org since 1998.

However, while the game can still be found at its .com URL, the .org domain hosts a completely different educational experience.

Although details are still a bit sketchy, it appears that sometime during the summer Ernst & Young lost control of the .org domain.

According to records, moneyopolis.com was (re-)registered in July this year by Ernst & Young.

Moneyopolis.org, on the other hand, was registered in June 2001 to a Mr Dave Web, based in Yerevan, Armenia. The URL also appears to be up for sale.

Moneyopolis.org hosts Euro Teen Sluts and is available in four languages.

In a statement Ernst & Young said: "It has come to the firm's attention that the moneyopolis.org URL, which has been outside of Ernst & Young's control for several months, has been converted by an independent 'Web developer' into a pornographic site."

Ernst & Young is warning parents and teachers to ensure they access the correct site and to change any bookmarks they might have for the .org site. ®
