Unfortunately there are thousands of people that do not believe the Mccann's story. People intelligent enough to see that there is very little evidence to support the abduction claim. Its not that these people wish for Madeleine not to be found,its that they wish for whoever is responsible for her disappearance to be brought to justice.
Hmmm ... which explains why people like you and Stephen in the post above continually harp on about the cost of the search for Madeleine McCann. You really want her found? ... strange ... when her parents were the only ones financing the search for her ... everyone was carping about the FF set up to finance the search.
It is about time the 'thousands' of trolls who are hounding Madeleine McCann's parents and siblings recognised the rule of law if not decency and conducted themselves accordingly.
Hopefully some may soon find the law does have teeth... and the present poster girl of the movement Ms 'Sweepyface' who is not by far the worst offender is deemed to have suffered enough humiliation in her naming and shaming (and believe me, in the eyes of decent people she is shamed).
Someone somewhere is organising this and they too may be unmasked and challenged legally on their motives, who knows we may discover something very interesting which could tie in with your last sentence.
Might be why it has taken an outside complaint to 'out' these trolls - it maybe suited not to - give them enough rope etc. etc.
