Wikipedia isn't a primary source, and it needs to be verifiable.

So by definition it's not exposing any information you can't find in other public sources.

Whether it's notable and something that should be included is another matter.

In any case, I'm saying that if you look at the articles for Madonna, Bono, Jenna Jameson, Marilyn Manson etc. you'll find their real name displayed prominently.

We can't form our own opinion in this case, as the GP is deliberately keeping the specific article in question hidden.

But in general this seems like a thing two editors could reasonably disagree about.

As a matter of (English) Wikipedia policy the inclusion of personal details ("such as date of birth, home value, traffic citations, vehicle registrations, and home or business addresses") should not be supported by only public records. Proper names for those primarily known under an alias are not explicitly covered under this section, but there would be a reasonable case for exclusion.

For the section in question, see: https://en.wikipedia.org/wiki/Wikipedia:BLPPRIMARY
