Agree. It's weird that there's no mention of either Upwork or the OP trying to get "Robin" to pay what he owes... But it could be benign. In a complex and emotionally charged situation it's all too easy to focus on the wrong things.

... is "Robin" a pseudonymous reference to "Robin Hood"?

Robin is one of the gender neutral names that doesn't expose any information or bias beyond the reader's.

I've often used "Pat" as a name for a person where I don't want to imply one gender or another.
