Hey, I googled it and found a few opinions here there and everywhere, but I thought I'd ask on the official forum and get a correct answer.

So we have FCOB on farm, and decided to do a few sellruns and deposit the profit into the FC kitty for the upcoming expansion. A few people PMed me and insisted that we run them first before they pay. I declined, retorting that I wouldn't be held responsible for wasting the time of my static. I did however wonder that if such a scenario ever arose, where would either accountable party stand in the eyes of a GM?
For instance; if we sold a t10 run for x gil and the player we boosted refused to pay afterwards and vanished off into the mist, and I reported said player, what would be the outcome considering the circumstances were proven true?
