Rules should be sensible as to protect the organization and the player at the same time. Not arbitrary.
Well publicized, but ignorance alone isn't the only problem. Wifi and cell towers can have all kinds of effects on where your phone thinks you're placing a bet from. Geofencing can be pretty damned accurate, but it still fails, and at what point do you know if you're completely off property or not?
If a player has dinner across the street from their hotel and is "off property," but connects to their wifi because of an automatic connection, and bets on NCAA women's tennis, is that really worth a 6-game suspension?
Flatly, the logic says absolutely not. The "rules?" Of course, that is a transgression of the highest order.
