A list allegedly showing the contact details of members of the English Defense League (EDL) was posted online Wednesday by hackers claiming to be part of Anonymous.
Names, addresses and cellphone numbers of more than 200 people from all over the country are on the list. A group calling itself Anonymous UK claims those on the list are all senior members of the EDL.
The post said the EDL "should have expected this" and warned it to "expect more."
Prior to the list's publication, an audio message recorded with a computerized voice from Anonymous UK to the EDL was published on YouTube, accusing the far-right group of taking "advantage of moments of fear and terror to spread hatred and animosity."

It compared the EDL to a "pack of raving ignoramuses" and said the group's "constant belligerence" would further "only bigotry and segregation."
"You have angered us considerably, and summoned our wrath irrevocably," the message continued.
The group behind the recent publications also condemned the EDL for using the death of Lee Rigby, who was stabbed to death in Woolwich, as "another excuse to further spread your campaign of hate, bigotry, and misinformation."
Fear of an increase in anti-Muslim rage across the UK has intensified since almost 200 Islamophobic incidents have been reported following Rigby's murder last week.
Among those incidents were attacks on 10 mosques, as well as several protests by far-right groups over the weekend. The largest demonstration saw hundreds of EDL supporters protest outside Downing Street, where bottles were thrown and 13 were arrested.
