I've just had a similar problem with Quora. My surname is "Wildgoose". It happens to be one of the oldest English surnames from when people were given names after animal attributes. Geese were guard animals, and I have an ancestor known for his wariness. And so Quora demanded I stop using "David Wildgoose" and insisted I use my real name. Which it is, of course. Appeals pointing out that animal names were common and giving well known examples like Ryan Gosling and Michael J. Fox got me nowhere and so I told them to delete my account. Only then did they relent and accept I was using my real name.
