I feel you, I've opened a thread before about it also as I noticed many auctions threads are down rated (I'm not an auctioneer), and also my threads for advertising my cats gets down rated a lot for no obvious reasons.
I was only asking people to be fair though didn't ask to remove it as some won't agree with that and if you check the thread you will find some think it is better to keep it so not sure what is the solution.
Threads Rating and Fairness
But anyway Anna -as you would see if you checked the thread- made me feel good about it, they are just jealous, that's why they rate low
