Some trolls are easy to pick from their early posts, some take a while. I remember there was Hal (think that was his handle), picked him early and only observed from a distance his continuing ones till it became totally clear he had problems. Often wondered if the pics of his family were pinched from someone else's photo album somewhere. Eventually went too far and got banned. I think somewhere also there's a dark internet group who compete with each other to see who can last the longest and cause as much havoc as possible on forums. Some of course are the devious ones, out to see what big fish they can hook to invest in their new, never before heard of, or attempted by the mainstream manufacturers products. Always the product will be as cheap as chips and only they know the secret to it. One of those comes to mind easily.
