The chair of the Federal Trade Commission has proposed new rules to tackle the scourge of text message scams. If the agency's commissioners approve the rules at a meeting in March, providers would have to block robotexts that are "highly likely to be illegal," chair Jessica Rosenworcel said in a statement.

The FCC has yet to publish the full text of Rosenworcel's proposal. If adopted, it will force providers to block text messages that appear to be from numbers on a do-not-originate list. They include unused, invalid and unallocated numbers, as well as those that government agencies and "other well-known entities" say they don't send texts from. Messages from these numbers "are highly likely to be illegal and no consumer would want to receive them," an FCC statement reads.
