I'm surprised you guys ask about some obvious scammers like these. If you weren't a full-time member here I would start to get suspicious from your post but I know this isn't your intention.
I mean she screams scammer from a mile--her webpage is a mess, she barely gives any info about her services, and that blonde girl in the picture is a stock image model that I have seen a zillion times before.
And to anyone like me who knows about different schools and genres of magick there is no such thing as a voodoo witch coven--there is a wiccan witch coven but those who actually practice original voodoo e.g Haitian voodoo, are solo and do not belong to any covens (they might be members of online voodoo practitioner or magic societies and forums) but they rarely if ever form a coven.
