not sure what you guys are complaining about.
he is just trying to help getting money back by locating person responsible.

what is worst case that can happen to you? Nothing.
what is the best case? you get your investment back.

let say, you have information that no one knows. what are you going to do with it?
go the Chinese officials? get you own hunt going? or just nothing?

at least he is trying to get the person(s) responsible so all investors can benefit.
whether what he claims true or not, it don't matter if you are not taking any actions with information you have.

no point on barking at ourselves, when we all know what we want.

'GET OUR INVESTMENT BACK'

if you don't want to chip in, stay neutral. if you do, help out.
no need additional noise to what we are dealing with.
