Ad van den Berg is treasurer of the
PNVD and former leader of
MARTIJN. He has served a sentence for having consensual sex with an 11 year old boy, who was scaremongered into confessing after being indoctrinated with myths about AIDS and homosexuality. Ad can be seen being harassed at home in
this video, part of a documentary (in Dutch)
here, and as the subject of some neat photo doctoring
here.
