To be honest, I don't think this has ever come out as a good thing to do. There are a few examples of the taunting LeBron tactic being attempted. Most recently there's the woman in OKC who was telling LeBron to suck it up. At the time, the Cavs were winning by 7. They won by 23. Of course there was the Wiz who decided that having shirts printed (during the playoffs) calling LeBron a crybaby was a good idea, of course the Cavs stomped them in the playoffs and one of the more infamous incidents was of course the Toronto game where Bosh's girlfriend taunted LeBron through out the game. He used that as incentive to destroy Toronto in that game.

I can only think of one publicized taunt that ended in a loss and that was the Christmas game against Golden State.

Go ahead but taunt at your own risk.
