Yeah, it's clear that the Wikipedia article about Bill Johnson is being crafted by his handler.

What will be done about it, by Jimbo and the Wikipediot faithful, who tell us (sometimes on national cable TV!) that Wikipedia strives to maintain an unbiased and neutral POV on every topic within it?

Funny you should mention cable TV.......because Jimbo appeared on The Daily Show last night.
During which Jon Stewart joked that he'd like to be called "Batman" on Wikipedia.

And now today, repeatedly, random nerds and IP addresses keep calling Jon Stewart "Batman".
It's been happening anywhere Stewart is mentioned on WP: on his BLP, on the Daily Show article,
on the article for his old MTV series, and on the disambig page for the name "John Stewart".
Elsewhere too.

And here they are on Reddit, joking about it.

Colbert did this sort of thing to Elephant (T-H-L-K-D) years ago, it's not exactly breaking news.

And Wikipedia "isn't exactly an encyclopedia" either.
Because real encyclopedias don't have problems with people using their biographical articles to make stupid jokes.
