The existence of software like AOHell provided a parallel 'lite' version of the hacker underground that had existed for years before, based around bulletin board systems. Programs like AOHell played an important part in defining the 'script kiddie', a user who performs basic cracking using simple tools written by others, with little understanding of what they are doing. These types of programs had a tendency to have AOL accounts banned; and so most users were logged on to accounts they had acquired illicitly, either by phishing or a fake account generator.
