Hey... if she claimed to be Sri Dhumavati Mahavidya or another goddess with a similar appearance, I wouldn't quibble over her appearance. But, she claims to be Srimati Radharani, and Srimati Radharani is described as having a certain form and characteristics by which we can recognize Her, one of them being unsurpassed beauty (both physically and inwardly).
Not to say that Dhumavati Mahavidya is any less a form of divinity, but She is described as being ancient and emaciated (kind of like Vasantha Sai), while Radharani is described as having a moon-like face, skin like gold, eyes like lotus petals, lips like bilva fruits, and beautiful limbs (unlike Vasantha Sai). So, maybe she should claim to be another form of divinity that isn't described as being unsurpassingly beautiful... then I won't quibble over her appearance.
