Per Travis View of the podcast Qanon Anonymous the accounting department of Washington Post knew his real name, since they paid him for a column published under his pseudonym.

Plus here's his thread on it, where he points out that he publicly stated he was using a pseudonym.

There's some good pearl clutching in the article.

Also, this isn't a dox here, as he announced it live on stream, admittedly due to this article. And personally I'll just keep calling him Travis View, it's what I've heard him as for 3+ years.
