For account hacked I didn't saw any weird of it, he (@jezuz) just made one liner post since he came to this forum you can check all history post that he made, also there are some post on local forum (polski board),

first post that he made

and the last post he made

Also for alt account seems like impossible since some of these account wrote in Russian board




Possibly he can be seller (same as @coinlocket$ said) or just gave merit to someone else for no particular reason.
