I have a Masto.es account for practicing Spanish, but activity and engagement seems low when I check-in. That could be my own social circle there, though.

I could recommend mujico.org with a warning: we are a mixed group comprising Mexicans, Mexican-Americans, and individuals from other Latin American countries. Our sense of humor differs significantly from Anglo culture, and we don't appreciate filters when it comes to comedy. If you are very politically correct, you may be shocked quickly

Lemmy-wise admittedly none comes to mind at the moment. In fact this is the first time I hear of meneame, which is good to know so thanks!

Mastodon-wise there's Chilemasto, Masto.es and Lile, admittedly haven't paid attention to instance names to find others.
