I think the easiest and cleanest implementation would be via mission, especially if you could pick up those missions from that stupid Stop Slavery girl's home faction.
if you think liberty/freedom's stupid, Romeo , then you're obviously so full of yourself that there's no point arguing the point with you , nor referring you to things like the difference between common values in the Carribean sometimes defended by the more honourable of pirates , compared to what you'd get from the more supposedly civilized amongst whichever imperial power , not even neccessarily the spanish/portugese - but since you know so much about civilzation , let me ask you this ... CONTINUED AT END OF POST...
Before finding this social-feedback post tiring , i think the thread-idea is a good idea , although the effect in terms of factions, might be better as one that grants you a very small / per slave / proportion-applicable , rep adjustment with any factions that do not get involved in slavery in general...ive noticed the difference between missions from individuals UNDER a faction, and ones that seem by their description to be more of planning / need of a faction - sometimes individuals within a faction do things that don't seem right , and other complications with them could cause confusion / inconsistency. a smaller , but causing for a player , more clear list of who's who in terms of slavery , WHEN you return some , could aid those on either side of the morality of it , to see who they'd like to support , without having to get used to the factions there - while whichever faction is in control of a hub/station , might be a simple way of managing the universe in game-management terms , its kind of misleading , in terms of understanding whether or not a commodities markert is a free market or not - IF, by comaprison , there were free AND other categories of commodities markets , then you'd have another story - but with the simplification AND only-one faction dominating , even when in some systems, a 'dominant' one , is sometimes only marginally more influential than the next, and only temporarily , seemingly, in charge , from my experience, the game actually has PRIVATE movings , comings ans goings, behind the scenes so to speak , behind the commodities, all the time - so its more realistic , for any system to be able to have slavery there , since if one faction would choose to take the risk of doing it secretly , who's going to stop them?
the premise of the game is one of out of control growth and lawlessness / minimum laws 'needed' , for claimed legit business/es , ie , if some large group has enough , they can fund THEIR OWN , new claims / installations , and set the laws within.
that said , things change , so personally i think a more involved way of affecting what is meant to be happening behind the scenes , would make this less numeric-calculated , and then dynamic in both ways - both NPC driven, but also affectable - if Frontier went with that , one could then not only do humanist things like youre suggesting , but also affect decision making BEFORE it ticks over automatically - weekly , with the galactic power ? daily ? some short periods , some long ? that seems logical. whatever.
but basically yeah, a good idea - stats could even be kept on each planet about how many have been returned , in terms of potentials of events at systems/planets/orbitals/moons/whatever , needing minimums of the returned - involved general pop , beleiving claims about one or another faction or a G power , AFTER enough are returned , and the slavery identified , or, conversely , on a sys where it's legit , and a player is targeted , a minimum of AFTER returned , for revolutionary / dissenter / sabotage-oppertunnity locals , able to affect events on the planet. why's it always terrorist, at the mo ? what ever happned to good old fashioned sabotage without a scratch on anybody ? agh.

... annnyway , speaking of minimums, ok Romeo , where was i ... ah yeah ... let me ask you this, Romeo - if freedom/liberty isn't something civilization builds on / relies on, presuming your argument is that it creates anarchy / less sacrifice for great works / neccessary ... whatever ... then why were the PUNIC WARS so damaging to the Roman empire ... mmm ?
risk, when depending, on slavery , is a much greater risk , than various costlynesses / slowdowns , of other forms of labour.
desperation , not greed , is a different story.
you dont become, 'elite' , by merely kissing when it comes to your perception of who's in charge, power-wise , judging by who has more slaves / controls them - they are hgh risk , expensive , and make you enemies - drugs , entertainment , blackmail , there's heaps of other stuff far more lucrative to the more discerning criminial , both now , AND back then - failing to recognise this risk/cost , in the kind of thing that in the freed-gladiator's eye , might make you think twice - confidence is not only a achillies heel of emperors ... ordinary 'dilligent' citizens , betraying their own for a dinar , got betrayed by it too.
call that reliability ?
get over it.
does the princess seem "stupid" now ?
or are you so lost in your own self-Romeo, possibly pretending science didnt come from Greece, absurdities , that, 'stupid' girls are just dreamers , just wasting time, when then elder-knowers of more involved, bitter-and-twisted 'understanders' , of a more cynical reality , are the only reality that can exist?
like , ooo , i dont know, how about the many French/neo-roman-abuse / neo-christian ones over the years ... that've managed to CREATE problems for the hypocrytical amongst the supposed 'betters' , above you , the classes, in roman terms, elites, above you , that have done so so easily , and with support / allies , not only in common folk , but in and out of courts , in royalties themselves , in the rich , in the religious ... etc etc ...
ie , not only , amongst whome , would be so claimed, 'less' , able to understand , the claimed 'need' for slavery?
typical Roman rationalist, no doubt.
have we not punished your supposedly 'civilized' identity enough?
you are a embarrassment for a modern roman - when people could look up to rome for its administrative and scienctific contributions , they only SOMETIMES , had to do so while slavery was empire-wide , and even then , when we looked elsewhere for tech and longer histories , we eventually found it , elsewhere, knowing, the only temporaily rich , would not last forever.
the idea that all science and civiilization came from rome is nothing but a power-fantasy of those unable to admit enough of histories not their own. the more indolent and self-obsessed you become as romans , the more often things happening like you being unable to clean up rubbish in your OWN streets , you will become , and the obviousnesses , of public interest and common good , belittle inflated fools like yourself.
how much of your our-money-will-come-back-to-us , money , has gone to china, in similar comparisons of commonalities / common-good(s) , over the years?
& not every emperor was pro-slavery, by the way.
discriminate between Torvals all you like , but she's not the only galatic power that's anti slavery - it being in the systems of those who are , is what i was saying before - missions of PRIVATE , factions - not would be participations , of your then , 'better knowing' .
