What do you not understand? I interdicted an NPC with a high bounty, I gunned him down to 15% hull, and I finished the job by slamming into him but caught no reward.
Happy to explain, but your reply is found wanting.
In fairness, I had to re-read 3 times before I got all of that too. Your use of colourful illustratives is a little esoteric at times... very poetic I'm sure but requires greater than the normal degree of concentration.
Either way, yes you should probably get the credit for ramming damage, you should also get the credit for doing 95% of the damage then having someone else fire the "kill shot", and ramming an unwanted ship should make you wanted and more so if it explodes. For reasons best known to frontier (probably because coding it any other ways was very difficult and exploitable) they register the "kill" as performed by whoever shot the weapon that kills. If there's no weapon it's "accidental death".
