Quoting InfiniteVoid,

The correct name of that ability is Karmic Retribution. It applies 100/200 bounty on the person who killed the trade ship (depending on researched level) and I believe is also subject to the Persuasive Offers research subject (increases bounty purchased by 12.5%/25%).
Yeah i guess there could have been confusion between that and all the other advent karma based abilities... sorry.
edit
50 percent sarcastic at the pointless name correction
50 percent I guess you gave numbers so your post wins on statistical evidence.
no need to bite his head off mate, he simply corrected you, and maybe the info helps the OP. if you dont want to be corrected, dont be wrong, but dont be sarcastic and self-righteous because you were wrong.
plus, the numbers, whether useless or not, are an accustomed thing on the Sins forums. i personally, dont care about the exact value of shield mitigation against me, but some people do, they like doing the math and being able to know for certain how much punishment a ship can take before it gets nailed. given, here, i guess it does not matter but dont be sarcastic, its simply bad manners and poor forum ettiquet.
back on topic: i sometimes get the same thing, players keep raising bounty on me after i kill the pirates, though i cant remember if there were other players at that stage or not.
if it is a bug, i guess it should be fixed, if it was advent then you know the reason why, in the meantime, be happy hes spending credits on useless bounty rather than on more ships to attack you with
