The infamous hacker group Anonymous has struck again.

On Sunday, it posted the names and addresses of members of the extremist Westboro Baptist Church after the hate group announced plans to picket Sandy Hook Elementary school in Newtown, Conn., where 26 people were gunned down Friday.

Anonymous posted the following two messages on Twitter on the weekend: "Dear WBC Site Admin, you should really work on securing your personal infos. Er, too late..."

Earlier, it tweeted: "It's so nice of #WBC to provide the internet with a list of their twitter handles.."

The list of the church members, which also includes email addresses and work numbers, can be easily accessed on sites like armywtfmoments.com.

At the bottom of a story that appeared on now.msn.com, one reader posted: "Good for you Anonymous....These are not people....They are sub-human trash....For them to target ANY of these innocent victims and their families, is just further proof of that....There should be a petition passed around to have people like this ARRESTED and PROCECUTED for planning and/or disrupting ANY funerals, vigils, etc.....If there is a hell, everyone associated with this 'church' would have a first-class ticket to it."

Media reports say that hours after the tragedy, the group's Shirley Phelps-Roper tweeted: "Westboro will picket Sandy Hook Elementary School to sing praise to God for the glory of his work in executing his judgment."

On its website, GodHatesFags.com, the organization states its mission is to conduct peaceful demonstrations against "soul-damning, nation-destroying filth."

In the past, the vicious anti-gay group has picketed the funerals of U.S. soldiers and AIDS victims as well as the funerals of those who were killed in a shooting in Arizona.

Anonymous is also petitioning the U.S. government to recognize the Westboro Baptist Church as a hate group.

"Their actions have been directed at many groups, including homosexuals, military, Jewish people and even other Christians. They pose a threat to the welfare and treatment of others and will not improve without some form of imposed regulation," the petition reads.
