We have always had a few folks with agendas that are not healthy to investor interests, including a few sincere and honest traders. The termites have no investment interest but generally are obsessed with some other human frailty, hatred to the point of sickness in some cases. Some are simply looking for a life, for someone to recognize their existence like a petulant adolescent who finds solace in negative reinforcement.
The one saving grace of the termites is that when they do try to legitimize their presence by saying anything on point it is sufficiently transparent that even the new visitors recognize them. That, and the fact the termites post so frequently that it becomes easier to skip over the little puddles of bile they scatter around in their attempts to disrupt the board.
