the majority of glua coders enclaved into little social circles/cabals where they exchange exploits, backdoors (usually obtained by doing slimy shit [inserting backdoors] while trying to seem like a legit dev), & the same garbage hacks reorganized, recontextualized, and only partially updated to stand the test of time as far as gmod updates are concerned. most devs went on to paid ventures or just went on with their lives
