I keep finding my craver colonies in grave disapproval almost to the point of mutinous and i was just thinking if you guys have any tips on lessening the effects.

I have tried moving my pop in and out of planets and systems but sometimes its just not enough, i find minor factions sneaking in and triggering the Slave Driver trait and its taxing to figure out how to deal with it every single colony.

I've also tried dumping off minor factions into space when i get a spaceport BUT this doesnt work if i cant get any luxury resources to get a spaceport and it happens more often than not.

you have also some law:

ie: -one gave approval for orbiting fleet around system 

     -an other give + 20 approval but decrease by 10% your science production

They fixed it on release, the new tech just lets you convert minor factions into chum. thanks Amplitude!
