From the site you ref'd, the "facts" on "perverted justice":
Facts:
There are very few real facts that can be confirmed about the site perverted-justice.com. The secrecy surrounding the site does not allow for any public openness and that leaves very few avenues for confirming information. The following things have been confirmed by the sites daily activities.
Your phone number and address are posted for public view. You likeness will be posted if it can be obtained. Personal information of your family, neighbors and your workplace will be posted in the 'follow-up' forums.
Calls to your family, your home and your workplace are encouraged in the follow-up forums.
Corrupted-justice.com has found no evidence to suggest that PJ is an accredited organization, registered entity; for profit or charitable organization.
Corrupted-justice.com has found no evidence to suggest that PJ is endorsed or supported by any child protection/advocacy organization.
Corrupted-justice.com has found no evidence to suggest that PJ is endorsed or supported by any legal department, branch, state or federal law enforcement agency.
Corrupted-justice.com has found no evidence to suggest that PJ is endorsed or supported by any institute of higher learning, including any member accredited teachers or professors.
Corrupted-justice.com has found no evidence to suggest that PJ contributors and other volunteers have certification of any kind.
Readers of PJ are not allowed to view the pictures the baiters use in the chat. You have to wonder whose children are featured in these busts.
PJ members convince you to see the light by telephone harassment, stalking, sending flyers to your neighbors, harassing your employer and family, and have even used DMV information to aid them in their harassment campaigns in their follow-up forums. All the while stating that they do not condone harassment of any kind.
http://corrupted-justice.com/facts.htmlInteresting point about the use of children's photos in the bait ads. Still, the question is of justice and whether it is being served in this situation. I don't have a ready answer but I don't think the secrecy surrounding p-j is much of a criticism.
