I won't confirm, but I wouldn't be surprised if you know who I'm talking about (ads are still everywhere on many social platforms). She's obviously cracked the code to marketing to her own very specific audience, but the problem is that a lot of her audience tries to do the same thing (and thinks their audience is identical to hers)...and I think most times that doesn't work, since it's unlikely the same audience who stretched to buy the $2k product from the big dog (her) is going to double-dip for the smaller, novice entrepreneurs and marketers, even for half the price.
