What legal grey area? Every carrier I've worked with monitors the content of MMS and SMS and will block outgoing messages, per CTIA guidelines. Carriers are already expected to block SHAFT content and other misuse/abuse, and some will even return specific errors when this happens. It's unfortunate that the FCC is allowing T-Mobile to surcharge every part of the messaging lifecycle, e.g. I learned recently that T-Mobile surcharges carriers on both directions of traffic, unlike others who only surcharge to send messages to them.

Some examples of common spam blocks: unwanted content, SHAFT violations (including specific keywords), or originating address has been flagged for repeated spam content.
