/bant/ isn't from /int/, /b/, /s4s/
/bant/ came from /pol/
/bant/ was created when the /pol/ mods became tired of ignoring the cancerous risk/offtopic/b-tier/compass threads that continuously clogged up the board.
All of that shit was purged and placed into its own board (/bant/) as a cleanup effort.
