I had no idea people thought Ana was a bot until recently when people started accusing her of being one. She often comes to my server and she didn't seem that strange to me, she even wears the "girlshair" hat. When accused of being a bot she usually says that she is a human:
I don't know if she has done this before as I haven't been following this topic, but I thought I would post it here in case it helps.
She could just be a bot being guided by a human?
