look, the sefaradim do it. They DID NOT get it from the baal shem tov.
maybe other sects of judiasm got it from him, but we have our own mesorah for it.
oh and Yes, the baal shem tov was not sefardic,
although if he was the originator of nusach sfard (was he? dunno..) then he was heading on the right direction 🙂 JTOL
