As an example, a protracted forum discussion of annuities often brings a flurry of new registrations from insurance professionals eager to extol the virtues of their particular version of that product, complete with less than subtle hints to send a PM for more information. The reception these new members receive from board members is reminiscent of watching cats entertain themselves with a captured mouse. In fact, dealing with those who register on the board simply to sell something - be it financial products, snake oil or themselves via their own self-serving blog - is a form of entertainment the board has polished to an art form.
