If I'm understanding you correctly - which perhaps I'm not - I don't know as I agree. Are you saying that the concept of "effective altruism" is "part of a consp..."?
The concept of effective altruism, as far as I know, is simply to maximize the good-accomplished-per-dollar. In the past, after being pointed there by proponents of effective altruism, I've donated to organizations giving malaria nets, etc.
If you are saying this, I'd appreciate knowing more about what backs up your claim.
But if you're saying that there's some entity cloaking itself as 'effective altruism' but carrying out a Ponzi scheme, then that I'd have no opinion on.
