Just go to her own website at sylviabrowne.com and notice how it is totally geared towards making sales at every turn.
No matter what page you click on, whether it is trying to get you to purchase readings for $775+ a pop, or spend money on her books, videos, lectures, hypnosis sessions, show tickets, "spiritual" jewelry, a subscription to her newsletter (which is not free), and anything else of any substance on the website which can't be accessed until you have paid for it, that's all there is, advertisements for her menagerie of dubious services and products that she wants you to buy with cold, hard cash.
And, most significantly to me, you can't even post anything on her message board without purchasing an "Inner Circle" membership first! It's all just one big online commercial designed to feed her pocketbook by any means possible, and to ensure that no dissenting opinions or bad reviews will ever be aired on her own website.
So it's obvious to me from that standpoint alone that she does not really care about helping people or having any honest discussions with anyone about her abilities, no matter what she might say to the contrary when she's on TV. The proof is in the pudding. All she actually cares about is getting money, money, and more money, from anyone who can and will fork it over to her. And no one with any truly spiritual gifts or connections with benevolent spirits or gods such as those that she purports to have at her disposal would ever have the need or desire be like that.
And then she has the nerve to accuse her critics of being materialistic just for being skeptical of her wondrous claims. What a hypocrite! At least James Randi doesn't charge any fees for the privilege of being allowed to make posts on the message board at his website.
