afreytes 🇵🇷Should I tell people to use the "post language" feature for when they post in different languages?
I try to mark my Spanish posts accordingly. (I might have missed a few here and there).

@afreytes If I notice it (and it doesn't just seem like a slipup) I usually send people a DM with the following text:
"FYI: Your posts are flagged as <LANG> (and therefore every reply to it will be as well, unless manually changed by the replier). You can change this under: Preferences > Other > Posting Language
Currently your posts will not appear in the public timelines of people who only enabled English posts in their settings."
