Try this one:

DEAD-BALL LIVE-BALL FOULS

4.19.14 SITUATION:

What type of foul is committed when: (a) during a deadball
period A1 taunts B1; (b) B1 crosses the end line and fouls thrower A1; (c)
immediately after the ball passes through the basket, airborne shooter A1 fouls
B1; or (d) B1 reaches through the end-line boundary and slaps the ball from the
hands of thrower A1. RULING: It is an unsporting technical foul in (a) and an
intentional personal foul in (b). There is no score in (c), as A1 has committed a
player-control foul. The foul in (d) is a technical foul charged to B1.

According to the definiton provided in 4-19-14 an unsporting technical foul is NONcontact, so the taunt has to be free of contact.
