Trolling
Many of the Slashdot trolling phenomena posts started out on Segfault. During its earlier days, Segfault would allow anybody viewing the site to comment upon the stories therein. Such comments were visible to any other visitors to the site, and initially tended to expand upon the themes within the story and add to the humor. However, as time went on more of the posts were troll posts (such as naked and petrified posts) which added little to the site. However, Segfault lacked any mechanism to remove trolls and their posts - unlike Slashdot and its moderation system, or Wikipedia's system of peer review.
As a result, the comments became ever more offensive. Eventually the operator of Segfault was forced to disable the comment feature.
