Do Unity projects contain identifying information?

Does a Unity project contain any information about it's creator or their account? Could someone who knows enough about Unity take a source project (or a built game) and get the creator's email address or Unity account name, or any other information that could be used to identify the creator of the project?

I asked this question on the forums (didn't get a definite answer) and there was some concern I was planning to do something against the Unity license or illegal, so I'll give a brief explanation of the situation:

I have a Unity Pro license I use for professional work. I plan to create or contribute to some side projects that are nsfw, and if there is identifying information in projects, I don't necessarily want my professional account name or email address connected to these projects.
