That $100 deposit thing is odd. The Alicia Lin I knew didn't ask for a deposit, so maybe you could be right about the scammer. Either way, I wouldn't be bothered pursuing a booking with a private who wants a deposit in advance.
If it is the same girl I don't know what she'd be like 4 years later but my god she was amazing back in pre-covid days. The bolt-ons were a bit too large for my liking but everything else was first class!
