Even though it looks like an alt account, its hard really to find anything as so far he has been pretty careful and doesn't have too many posts yet  (altough maybe too eager in his farm merit attempts which got him unwanted attention.) and he posts mainly in Spanish so rest of us that don't speak the language can't really help determining whether he is a native speaker or just using some of those AI tools.

My advice for you is to keep an eye on him and especially on the adresses that he us using as soner or later, many of them slip up.
