Well, from the rules, bold text by me:
4) Removal From The PL
a) If the accuser requests the accused be removed form the PL, the accused will be removed.
b) If the accused makes full restitution to the satisfaction of the accuser, the accused will be removed from the PL.
c) If multiple accusers are involved, and full restitution is satisfactorily made to all accusers, the accused will be removed from the PL.
Alex went through a LOT of difficulty and stress with this transaction. I for one would not blame him if he felt unsatisfied and saw no reason to remove GP. I'd also wager that GP has already made it to a number of folks' personal "do not deal with" lists.
