Some reasons:

As you said, really obscure. It appears to be an out-of-date (the website ended in 2014 and the show was long before that) and very niche wiki.

Only 6 pages. If you want activity, there needs to be content. So far there's only some poorly written articles with no clear pattern.

It's relatively new.

That's about it. Give it time, and maybe, maybe somebody interested will do something. But for now, don't bet on it.
