But what is unfair in that, really? At worst, it wastes peoples time when they bid and don't know about hidden reserve price.
That sounds quite unfair. Not disclosing the reserve price or even the existence thereof makes people waste their time and perhaps miss other opportunities. I can see how that makes Vod think you're not trustworthy.
Having said that, this is not even your actual problem. Your problem is retaliating with a butthurt neg against a factual neutral rating AND now whining how the trust system is abused. Do you really not see the blatant hypocrisy of that?
