[Ref in PA]

If the defense were to use this tactic for an advantage such as:

A1 steals the ball and is at mid court on his way for an uncontested lay-up. B5, steps oob and says to the old lead/new trail "hey ref, I am oob." Tweet! violation. Put ball in play at the BC end line because that is where the violation occurred?

or

Team B wants a time out but Team A is in control of the ball, B1 steps oob to get the violation. Team B did not have to foul to stop the clock and get the TO.

or

Team A has the ball in front court. B1 runs to the far end line oob to commit the violation. Tweet! Team A now has the ball for a spot throw-in at the far end-line. They could make the team keep bringing the ball up court time after time - an effective strategy at the end of the game to make a team burn time.

Maybe we have the latitude to interpret these plays and others as unsportsmanlike conduct and call a "T".
