After members of the Westboro Baptist Church announced yesterday they would be picketing the funerals of Boston Marathon victims, Anonymous-affiliated pranksters preemptively hacked the church's official Facebook page by replacing the timeline with jokes and image macros expressing love and tolerance. As of 6:30 p.m. (ET), the page appears to still be under the control of hackers.
UPDATE (8:15 p.m. ET): The page actually appears to have been spoofed (also known as "brandjacking") and was never actually owned by the church.
