Blackmail was paid by the tenant or farmer to a "superior" who might be a powerful reiver, or even an outlaw, and in return the reiver not only left him alone, but was also obliged to protect him from other raiders and to recover his goods if they were carried off. It reached the proportions of a major industry, with the blackmailers employing collectors and enforcers {known as brokers}, and even something like accountants.
