Many posts inaccurately tagged as langs: ['no']

Steps to Reproduce

1. Go to https://bsky.app/search?q=https and switch language to Norwegian -- or simply https://public.api.bsky.app/xrpc/app.bsky.feed.searchPosts?q=https*&limit=10&sort=top&lang=no
2. Observe that many posts are in fact by Japanese accounts in Japanese, but the posts are tagged with langs: ['no']

Additional Information

Speculation: since this appears to be much more prevalent for Norwegian than say Swedish or Danish -- could it be the 'no' being a falsey value in some languages could affect things?

Hello, having looked at this issue this looks like a user error.

I wasn't able to reproduce this by creating a post solely in Japanese, but I was able to set multiple tags for a post which is what the users were doing.

there are other cases where a similar case is true, for instance, when filtering by Danish, i get the following english post, tagged with the da tag, despite being only written in English: https://bsky.app/profile/jacobchr.bsky.social/post/3licl3lvidb2w

It would be expected for Europeans to frequently reference and link to English, French and German medium sites, far less so Japanese...

Agree that there is a likely user error at the poster level, so maybe the problem is less the feeds and more the UX of the app?

They're likely using TOKIMEKI, a Japanese multi-column client, which by default intransparently (and badly) tries to auto-detect post language when creating a post. It usually attaches the top two or three matched languages.
