Reminds me of tapelooping and blacklooping. Not only urban legends were spread by fax. All sorts of scams, baseless legal threats, harassment, and more were too. Since in theory it tied up meaningful resources (time on the phone line and potentially paper and ink) some places made sending certain things by unsolicited fax illegal. In the US IIRC one could be fined and be made to pay restitution and punitive damages to to recipient if they could find and name the party to the government.
