LOL - instantly kills streets gangs in the streets (well some gang don't work) use alt.
hand - completely kill all street gangs including mission gangs - alt.
curse - instantly kill all the people execpt grove street gangs

place them in the cleo folder - it's useable for gta underground that gangs anoneys you and kill to prevent crash.
this will block all the gangs and you'll have gang-free zone but you will no longer takeover the hood.
