A convicted Islamic extremist in Indonesia running a popular jihadi website has been profiting from revenue generated by online advertising platforms according to reports.

Muhammad Jibril Abdul Rahman, whose website Arrahmah.com featuring pictures of beheadings has garnered 600,000, and on occasion, upwards of 1 million visitors, a month, has been using platforms such as Google’s Adsense to feature advertisements from companies such as Microsoft, IBM, and Citigroup, according to Britain’s Financial Times.

Jibril also dubbed the ‘Prince of Jihad,’ was sentenced to five years in prison for his role in the 2009 bombing of Jakarta’s JW Marriott and Ritz-Carlton hotels that left seven people dead.

Jibril was accused of knowing about the plot, aiding the bombers and forging documents.
