[Meta] Should the trend of users posting Android questions on here be curbed? If so, how?

I follow this subreddit because I care about Kotlin, the language. I understand that Kotlin targets Android, but there is seemingly a neverending trend of users asking Android-only questions that are against the rules and are more appropriate for r/AndroidDev or related.

Given the fact that too many conflate “Kotlin” and “Android,” what should be done about these questions? And why are moderators not removing them in the first place?
