Almost all prossie responses to negative feedback can be disregarded as bullshit.
There is very little fake negative feedback from punters on AW (you can often confirm this by looking at UKP reviews), for many reasons, one being they're at risk of getting some in retaliation and it'll affect their ability to arrange bookings with other WG more than it would for the WG to get bookings from new punters.
Some girls with lots of positive feedback might get a very small number of negatives but quite a lot of girls don't (it seems more than you think even though they're definitely not perfect). Anyone with less than 95% positive feedback is likely to be crap. The only major exceptions are when girls have very low total feedback but on the flip side girls with lots of feedback (e.g. 200) who have 5% negatives (e.g. 10 negatives) are also likely to be shit (their negative % should be much lower). Of course, it does also depend on what the negative feedback if for, e.g. if it's just for no-shows/let downs then it doesn't necessarily mean her service and appearance is shit.
Having said all that, one fairly obvious reason that I don't think has been mentioned so far, is that the booking may have been confirmed before it actually took place (many WGs seem to do this) and then it never happened (for whatever reason, e.g. cancellation or radio silence from either party), so they might actually not have seen the punter but in those cases it's very unlikely the punter would have left unfair negative feedback. As I've said, in almost cases it's lies from the WG.
There are some odd people out there that do cry strange things. Some guys will lie and leave bad feedback, some will leave positive feedback even though they haven't met you, and we know some will leave positive feedback when it should be neutral or negative.
One of my first was a guy who gave me positive comments (feedback only as I didn't confirm the meeting on AW) even though we hadn't met. He cancelled and told me he wanted to leave me positive feedback anyway to help me as I was quite new and didn't have much feedback. I told him I wasn't confirming and I told him not to write anything, but he left the feedback anyway.
I remember quite some time ago I gave a guy negative feedback and I just wrote one word...disingenuous. He retaliated and left feedback saying I was one to avoid. Guess what happened quite a few months later? He contacted me again to arrange a meeting, apologized for before, offered to pay me a deposit so I would know he was serious. He offered the fee in full, I told him I just wanted £50 but he sent me the whole fee anyway.
On the night of the meeting, I waited for thirty minutes, he didn't contact me and I couldn't reach him so I left. The guy threw away £250 quid. Well, great for me obviously, but just goes to show there are weird things that happen.
