One of my neighbours is on my fb list and has posted a status asking for the door number of a paedophile in our small village and listing the street he lives in and who he lives with.
Obviously if I can work out who she means then so can everyone else, I already knew about his conviction and so have put my own safeguarding measures, ie knowing where dd1 is if she plays out at the park, arming her with a mobile and stranger danger talk as well as making sure she's always playing out in a group.
IMO I'm forewarned and can protect my children accordingly, I don't think a witch hunt is nessersary whereas everyone else who has commented are baying for blood. Fwiw I also know about another paedophile in the village who abused a member of my family decades ago, but I don't see the need for hunting and singling them out. They have to live somewhere and I'd rather know than be blasé about the whole thing.
Sorry for the ramble.
