My wife did just share she recently gets reddit at the top of long-tail searches, and I _believe_ her primary search provider is Mojeek.

I said recently, but I meant "frequently". Too late to edit, now.

I'm sure some of our providers do, but I can check, if you don't want to. What would be a search that would reveal that?

We (DuckDuckGo) does if you add reddit to the query; that forces our reddit module to show.
