It's certainly satisfying that you're beginning to see this, but .. As far as I know, you're 5 years too late.
The people who follow this tripe, are already lost.
The only way to save those who've fallen for this, is to "kidnap" them and give them the usual "secterist deprogramming"-treatment. It works, but is very expensive and only works on one individual at a time.
Personally, I gave up on the "andromedan council"-people years ago. They are no more or no less difficult to deprogram than kids living under ISIL-rule.... Each person will need a personal instructor and for years to come.
Although, It's cheaper, and more effective to simply just let a few of them die, in order to teach the rest that their sect is no good.
