Should an AP help his follow players to learn more about barrings in AC casinos? Sure. I like helping, It's good karma. A helping hand and good karma always have a way of coming back to you.
As this old saying goes: 'Learn from others' mistakes, you are not going to live long enough to make them all yourself'. An AP should try to avoid barrings in AC by learning from other APs' mistakes. The Morse case is a good example for us to learn from. Expert Tracker David Morse has been barred from AC casinos because NJCCC "BELIEVES" that Morse is a "cheater", not a tracker. So don't give casinos & NJCCC any excuse to bar you. Here's the case info & photo from the NJCCC's barring file:
"Morse was videotaped by casino surveillance departments at Trump Plaza, Taj Mahal, Caesars, TropWorld, Resorts, Bally's Park Place, Bally's Grand, Trump Castle, and Sands, as he tried to influence the game of blackjack by manipulating or attempting to manipulate the cut card in the deck to determine what card would be the first card dealt. Rather than place the cut card back into the deck in the manner required, Morse would place the cut card in the deck in a manner that would enable him to determine what card would be dealt to him after the shuffle, thus giving him an unfair advantage."
