The earliest I can trace it back to is this post to comp.lang.ada in 1994:

I like how he opens with "I felt like wasting bandwidth" so here's a funny story. Little could he imagine it would become #1 link on Hacker News, 15 years later :-)

Maybe something like 「金持ちのダンディなおじちゃん」

This is actually an old idea from early in Wikipedia's history:

"It was hoped that scientists would sometimes drop by wikipedia, and start a stub or short article on something they had researched, prior to it being accepted in a peer reviewed journal. This would allowed a scientist to prove that they discovered something first."

As that page also notes, the very strict interpretation of "No original research" of the modern Wikipedia community makes this very difficult.

Even pages in userspace pushing what is deemed OR are liable to get deleted, though not nearly as much as in articlespace.

I think you mean 申し訳ありません (inexcusable).

Though I've tried using 申し訳あります (literally, there is an excuse) before as a joke to lighten the mood when apologizing. I'm not sure they got it.
