This post from another thread sums it up:
There have been quite a few threads lately which look like they've been started by trolls wishing to get a kick out of discussing child abuse with other posters.
There have also been other threads which have had a dubious intention too, not sure whether to name them, as I don't want to this to be a TAAT.
Has anyone else noticed this, because if MN us genuinely being targeted by paedophiles, I don't think the standard "OP seems genuine" type monitoring is sufficient.
