Jehovah's Witnesses. Did Jesus disfellowship or shun people?

i think jesus' rule of thumb was to forgive one another 77 times. so, i guess we are supposed to believe that all shunned or disfellowshipped unrepentant sinners have practiced their own particular type of sin at least 78 times. probably, someone is igned to keep score so to speak until the magic number of transgressions is reached.
