The interesting thing with charities is that they have a special status. In return for lenient tax treatment and a few other privileges, they have to show public benefit. Everyone involved has different forms of accountability. Were one to commence a campaign on this issue, it would be a matter of finding who or what holds each of the various perps to account or at least constrains them (eg. rules on proportionality and non-discrimination, professional standards bodies, judicial review Ombudsmen etc) and then being rather relentless about it. But the starting place has to be simply asking.
