PlayStation Lifestyle reports that Anonymous has clarified its position regarding attacks on Sony over the abhorrent SOPA law -- keeping in mind that Anonymous isn't a strongly cohesive "group," and so it's not entirely possible to ascribe a single point of view to it.
The opening message on the group's "#OpSony" IRC room was reportedly changed to "NO SOPA! NO ATTACK ON PSN!" In an area for planning "ops," the group suggested that "Doxing [posting personal documents] will occur on Sony executives." Other avenues of attack included hacking Sony websites to place anti-SOPA material.
This attitude is consistent with statements previously attributed to the group, expressing a desire not to inconvenience Sony customers while carrying out protests against Sony.
