I agree, incorrect identification of a target can be a problem. The last time i tried one of these missions it was a simple "kill 2 Pirate" mission. After meeting the guy in a USS and ignoring the abandon i then spent a fair while pulling targets out of supercruise, killing them at nav beacons, killing them in USS. In the end, once more i gave up, i had made just under 120k in massed bounties but still had to just leave the mission to time out due to the target count in the mission not advancing. I will also add that this was a 1 system hunt and not a multiple system hunt and the "nail in the head" for me and these missions
Why every single one of these missions needs an "abandon" is beyond me, i accept missions as i know i can do them, i don't accept them to abandon...
