Quickseller has even backed off and changed his to a neutral. The fact that Quickseller thinks it is appropriate to do so, yet you still resist, is quite telling.
I changed my negative to a neutral because he is no longer offering escrow services. From my viewpoint, the OP probably saw that people are charging for their escrow services and wanted to earn some money in a similar way.
Once he was explained why this is a sign of him being a scammer, he quickly corrected his actions and closed his escrow thread. I think he most likely didn't know the "rules" regarding when it would be appropriate to offer escrow (and yes they are unfortunately unwritten and they do change from time to time based on the community).
I think your actions are appropriate. This is the difference between going around spraying and praying with ratings and actually critically examining your ratings such as people like Tomatocage. This war mentality against people who likely just don't have a clue how things work here needs to change. It doesn't serve anyone (except the trust vigilantes).
I only mentioned you Quickseller because you are some one who regularly gets accused of going too far with your ratings, and even you are reconsidering, putting Hilariousandco below your standard, which is the telling part to me. You don't always make the right call but you (usually) will reconsider ratings if some logic can be presented. The rate at which Hilariousandco has been leaving negative ratings has accelerated lately. It seems to me Hilariousandco wants to be Vod v2 and just do it shotgun style and not worry about where they stray shots go.
