Hi Taz, I subscribed to dsrwatch to monitor my DSR as soon as I saw it on Auctionbytes (I believe) to keep tabs on my own ratings, whilst sales a little slow I can pinpoint back stabbers and leave feedback accordingly as I only leave feedback after the buyer.
And it is during slow times you certainly don't want the odd malicious buyer to make things worse.
I then block major backstabbers, plenty more fish in the sea.
