T for a flop?

[Rufus]

10-3-6f - A player shall not commit an unsporting foul. This includes, but is not limited to, acts or conduct such as faking being fouled, knowingly attempting a free throw or accepting a foul to which the player is not entitled.

The penalty for any of the above is a player technical. My question is concerning the bolded section. Has anyone ever called a T for a flop/fake foul or is that about as common as a 10-second violation on free throws? What would cause you to even consider calling such a foul - if the shooter/ball handler was disadvantaged by the flop?

Got thinking about this recently and couldn't come up with a time that I would consider calling this even though it's a rule. It irks me that it hasn't occurred to me to call this and wonder if it's more prevalent than I think it is.
