Most all recommendation algorithms definitely do not care about locality of reference.

If I watch some local-to-me news stories about libraries, the algorithm decides that I like news about libraries, and begins to suggest library-related videos from all over the USA. It does not care that I only cared about libraries in Phoenix and San Diego.

Likewise, there is this one English teacher who is absolutely gorgeous and I only watch her videos to see her talk. But of course, YouTube got the idea that I like English instructional videos from anyone, anywhere, and the algorithm slowly fills my feed with videos from instructors who are not the lady I like. It's crazy, I tell ya.

I'm not on FB anymore. But when I was, I got interested in Irish topics, and it was often family research-related, and so I'd be studying some esoteric topic in a very small town in a specific county of Ireland, and of course, the recommendation engine would blossom with completely irrelevant Pages and Groups from every corner of the Republic, for no reason except to bait me into engagement.

And that's all it is, engagement bait. They on the other side of the algorithm, they know for sure that you don't actually care about those topics or locations. But they are simply trying to dangle stuff in front of you like a largemouth bass, and eventually something will enrage you or you'll need to correct someone's spelling, or make an angry face emoji on a post, and then they have your engagement, and that's all they really wanted from you.

Not to inform you, or entertain you, but to engage your shit until you absolutely lose your temper. That's what they want on social media.

There's your mistake. You need to be watching Spanish teachers.
