This was probably unintended, but giving his real name in your article also marks a precedent.

Even though it was well known in Ruby circles, it had never been published in the press. Now that it has been, his Wikipedia page has been updated accordingly (now that they have a "reliable source" in Wikipedia parlance), which exposes his identity much more than it used to.

For that reason, I wouldn't mind if you redacted his name, the name of his employer and the way you found him out of the article. The same goes for the mirror of the infamous wordpress page.

He made it clear that he wants to be left alone. This doesn't help.

Edit: the mention of his sister was also completely out of place.

Temp account, Noprocrast prevents me from editing and making my point more clear.

Until today it was not possible to discover who he was without searching for it. Now you get to know it even if you didn't want to.

The Wikipedia article is the first Google result for his pseudonym. Now his real name is in the SERP. Good job.

His sister figures prominently in the most popular Ruby guide!

From the book, it's hard to know where fiction ends, and where reality begins.

It could have been about the imaginary sister of his persona, or not, but it wouldn't have mattered as long as he was anonymous.
