I must admit that I was doing a similar thing at one stage because I got so pee'd off at buyers not reading all my listing text and/or not fully understanding what they were buying.

They would simply leave negative feedback without any comms first.

But as time went on and the feedback went down the page, and things went smoothly again, I felt silly and removed it.

It's just a few rotten apples amongst a very good bunch of buyers who can have the power to drive us crazy.
