I got a similar hit on Wikipedia when I tried to start the article on a company, which happens to be a YC alum. I was just comparing VPS providers, I knew this company was in the space because of HN, and noted the hole in Wikipedia, so I started the article as a way to fill in my own knowledge. Ho. Lee. Sheeeit. There were some admins looking to grind serious axes about "commercial influence". Yet I was behaving more like Consumer Reports. Job got done, but wow.

I tried to limit the snark, because parent's not wrong. There's a ridiculous amount of astroturfing out there.

I haven't had too much experience with Wikipedia, but I absolutely believe your story. Their hierarchy is... interesting.
