Absolutely, S2srea.
That is how the devil snares people. They haven't just posted their theories on a message board, they have turned it into a cottage industry -- their virtual identity. No anti-BoD, no Dimond Bros. Their livelihood is also based on what they're doing, selling books, probably asking for donations.
I say nothing about the Dimonds specifically, but not only will people sell their souls for power; they will sell their souls for imagined power, power they don't really even have, or for the chance at power. It can become an addiction to be talked about, to be noticed, even if you're being noticed for the wrong thing.
There is a reason certain saints would flee from the priesthood and would try to escape and go wash dishes or something. Look at how many priests went along with Vatican II, who didn't buck the tide at all. You have to be ready at all times to walk away and leave everything if your faith is compromised.
Some people are made famous by God; others make themselves famous. He knows who He is raising up. But sometimes to us it can be tricky to figure out who is a sham and who is truly called.
