The context of the quote cited in the Oxford English Dictionary sets the origin in Usenet in the early 1990s as in the phrase "trolling for newbies", as used in alt. folklore. urban (AFU). Commonly, what is meant is a relatively gentle inside joke by veteran users, presenting questions or topics that had been so overdone that only a new user would respond to them earnestly. For example, a veteran of the group might make a post on the common misconception that glass flows over time. Long-time readers would both recognize the poster's name and know that the topic had been discussed repeatedly, but new subscribers to the group would not realize, and would thus respond. These types of trolls served as a practice to identify group insiders. This definition of trolling, considerably narrower than the modern understanding of the term, was considered a positive contribution. One of the most notorious AFU trollers, David Mikkelson, went on to create the urban folklore website Snopes. com.
