I completely agree with your whole post but the quoted section is most important. As annoying a phone checking is, it's the best way to avoid getting screwed.But whatever the reason, you can only just be a good example and protect yourself from getting taking advantage of by one of these types of players.
With all that being said, it should be noted that being the shop's securities and exchange commision is going to infuriate the rest of the players, and no one likes a narc (or maybe that's just st. Louis, aka just shy of detroit). The key is to CYA, and maybe keep an eye out for newbs if the angel on your shoulder gets too loud and obnoxious.
