thats what i was thinking as well... it seems for the us, its mostly about spam prevention and marketing messages (referred to as SHAFT in the link below)...
seems not intended for individuals but those messages intended for commerce?
Those guidelines make sense, but they're not just blanket keyword bans.
For example, it would violate their industry standards to send messages like 'Cool your thirst! No-ID beer sales in your area, reply now for $5 off your first 12-pack', sent out as a bulk message. But if I just message you saying 'wanna go for a beer later', it's not a commercial message. These guidelines are to prevent spam that might fall in one of the SHAFT categories, not to police communications between private individuals.
