To file a complaint with the police in Pietermaritzburg, I don't think it would necessarily have to mean having had direct contact with the Desteni group, but it would have to be based on facts to make it worth their while in terms of being able to identify criminal activities.
The Desteni scam is at least to some extent successfully being deterred by a number of individuals online as they are providing factual information and reasonable ideas about it, not setting off false alarms. Unless somebody is keeping it secret, there is no evidence that Poolman or anyone else in Desteni are sexually abusing minors. There is not even evidence that people under 18 are visiting or live on the Desteni farm. Poolman's aggressive stance against the world could be such that he is in possession of illegal arms, but again that is mere speculation.
As freespeech4tw pointed out, there's something very adolescent about Desteni media, and that's the case whatever the age of those involved.
There are now a great deal of videos released by Desteni which are supposed to convey the idea that parents are "evil". They are deliberately aiming to recruit young people with problems with their parents.
The age of the ex-Desteni member who ran this currently inactive YT channel:

and contributed to this forum is given as 22, so he was only 17-18 when he got into Desteni and paid out for their Structural Resonance Alignment Training.
It could be that parents' money is being used without knowledge of what it's being used for. It could also be that Desteni websites and courses ought to be bound by law to have an adults only policy. In which case, their web host or some other internet authority could be informed.
