Hi Shawtay!
I had so many doubts about this game too, so I tried by myself.
First: I feeded the pork less than 10 times and kill the Fat Porkerwith a team and after we killed I got the following message: "There you have it, the porker is gone pork for everyone! Did you feed it enough to ear your share of festive points?"
Second: The second try my friend feed the porker and I just help him with 50 foods and once again same message:
Third: And the third try and last try. I feeded the pork by myself and this is what appears:
So by this I could say that the message doesn't means any judgment, to check you points you will have to check with the NPC: .
I also realized that the faster way of get the food is without kill the orgers just running ans taking food on your backpack and use it with hotckeys to feed the pork fast.
