Remember that this whole issue started with Jack having the balls and sense of UKP responsibility to post a negative review on a well-established and generally well-regarded WG.
Would Phoebe have independently contacted him and made this offer? Categorically no, and prior to the review there was no indication of that. However, she did not try to deny, discredit, counter-claim, send in the fanboys, or any of the other histrionic responses often posted by criticised WGs. Instead she verified and acknowledged what had happened, and then made an offer to compensate Jack. I viewed that as a positive result and an indication that this forum can make a difference.
I think the best course of action following the compensation punt would've been for Jack to add a couple of paragraphs to the original negative review to state that Phoebe kept her word and he had a good time. He could also have changed the wording of the original title to reflect what had happened and asked Admin to change this. A new review was always going to be tainted by the context surrounding it, and was open to the criticisms that (inevitably) followed.
Does no-one read VW's posts! He was always likely to respond to this negatively with criticisms, insinuations, and the old "have you been here before" chestnut. He acts like a bad copper firing circumstantial evidence to try and trip people into saying something more incriminating. I'd like to see him change his nick to Polly-Graph

. However, his contributions are well-regarded, and for all the times he may get it wrong, he has uncovered a number of wrong-uns. It's all part of being on here, so carefully consider before posting.
