Unsportmanlike Conduct: Flopping

[João]

Hi all, while I'm here I'd like to pose another question about basketball rules regarding flopping. In soccer there is a big problem with players falling (called diving or simulation) with no or little contact, embellishing the play in order to get a foul called (most notably in the penalty box). In order to combat this, soccer officials will award a yellow card for USB if it is clearly a dive.

So, my question, could this be called in a similar fashion in basketball? IE. A1 receives the ball in the low post and moves slightly backwards toward the basket. B2, his defender, is defending him very closely and upon A1 receiving the ball, B2 flops violently backwards, obviously falling with no contact.

Say there is no advantage to the player falling down, can a technical foul be assessed for such unsportsmanlike conduct?
