Might as well add mine for the record.
Reasons why I don't believe in AA anymore:
She did not make a claim until someone at the asylum gave her the idea with a book
She first claimed to be Tatiana
Her story of escape is unbelievable and cannot be proven or verified. There is no evidence Alexander Tchiakovsky ever existed, and it sounds like a conveniently invented name (common first name, famous last name)
It is very unlikely anyone survived the brutal massacre, and if they did, could not possibly have lasted for long, traveling miles in a cart, with no medical attention. If they didn't bleed to death they'd succumb to infection later. It's what, almost 1,000 miles from Ekaterinburg to Romania? How many weeks is that by cart in the mud, hiding from populated areas? It's not realistic.
She doesn't look like Anastasia- fuller lips, wider mouth, wider set eyes, different shaped chin
Any of her 'memories' could be explained as being told to her, intentionally or inadvertently, by Russian emigres'
Even with these 'memories' much of what she said was inaccurate
The Romanov and Hesse families rejected her, and I don't believe they'd have been so cold if she were genuine
The Schanskowska family first accepted, then denied her, and later there is evidence they did so to avoid responsibility for a troublesome sister and as not to spoil her 'career' as 'Anastasia'
Many other acquaitences of the family rejected her as false. When she met some, she hid part of her face or stayed behind a screen so they couldn't get a good look.
with all the rumors of money and vast fortunes (which later proved false) there was the potential for 'gold digging' and 'supporters' backing her in hopes of a huge payoff if she could win
There are too many different stories and conflicting reports of things like her height, scars, what languages she spoke, and when she spoke them. Most of these stories are from only one source, often unnamed or unverified, and many contradict each other.
