Lazybot survived for years not because of the software itself, but because of the community that supported it. One user noted, "After you open the bot go to tab 'Behaviours' ... Since there isn't many class behaviours in the bot i highly advise you to create your own for every class". This DIY approach encouraged players to share custom scripts.
