Its common knowledge at this point. English wikipedia is guarded by an army of moderators who try their best to prevent new articles from being created.

I think that was little joke.

You know what I think is really telling? I think you're correct that it was a joke/meta-commentary, but I didn't even process it as such until you called it out.

And that's exactly why Wikipedia has such a problem with its editors. They're so good at getting their way while appearing to just have logical arguments, as has been stated elsewhere in these comments.

So that either makes it an incredibly on-point joke, or actually a statement that anecdotes aren't facts, and I can't even tell which for sure.

No, common sense is usually quite adequate.
