The US Federal Trade Commission is seeking public comments on its proposal to require sexually oriented "spam" messages to contain the phrase “SEXUALLY-EXPLICIT-CONTENT: ” on the Subject line, and to have "the electronic equivalent of a 'brown paper wrapper'" in the message itself. (The "wrapper" is what the recipient would initially see when opening the message. "It would include the prescribed mark or notice, certain other specified information, and no other information or images," according to the FTC announcement.) The period for submitting public comments ends on 17 February. Click here for the text of the official notice published in the Federal Register, including the address where comments should be sent.
