You are correct in saying that negative reviews are equally as important as positive. I think your colleagues are trying to highlight in an indirect way that it's unusual for a punter to have similar reasons for a negative punt. Also for you it's a costly hobby if your not enjoying it.. Have you experienced a positive punt as there is a wealth of if information on here that can help you with achieving that 
Hi Shed, I'm trying my best here and just trying to do the right thing in line with what the website requires & it's punters.
To answer your question regarding me having a positive punt, please see this thread and my reply to @alabama1
https://www.ukpunting.com/index.php?topic=452829.0 - I did try and answer as best as I could but just kept being trolled.
Yes, I have had a read through some great positives on here and appreciate the positive experiences shared by other users, and you know, if I had been seen on some of these punts by these ladies, my reviews could well have been a lot different...but, ultimately, I wasn't seen and not much more I can do about that than review my experiences as negative.
