 With avatars donning the skins of superheroes like Superman and Wonder Woman, the Justice League Unlimited established monitors in many areas of Second Life and zealously reported any untoward behavior to the Linden Lab administrators.The zeal with which they executed their duties, however, proved to be problematic and they were soon banned from areas such as FurNation for excessive vigilantism.According to cyber-rights researcher, Peter Ludlow, the Justice League Unlimited's anti-PN efforts also became problematic as the close association between 4chan users and Patriotic Nigras led to the unwarranted harassment of many users who were 4channers only and not members of the PN.
