Pm blocked? Is that doable in this forum? He's online right now, and I'm not sure how can you approach him. Maybe quote some of his posts?
You can block members from messaging you.
Serious questions, no trolling: Did he block you for harassing him about QS? Since Tomato acts as a escrow, I doubt he blocks many people so there has to be a reason why you were blocked.
Serious answer: I seriously doubt it. We discussed QS last time he was on his list and it was a very productive exchange of like 3 PMs where TC was able to convice QS to change his ratings to a neutral. I would be very suprised if he decided to block me after those PMs. Last once I received from him was saying "problem solved, please adjust your ratings accordingly" and I did so and changed mine to neutral as well
Let's see how long it takes for this thread goes from how to contact Tomato to QS is a evil man and should be removed from the DT list

I would like to avoid that. I found that public sparring with QS doesn't help and I'd like to resolve this nonsense.
