The dev team is either incompetent, indifferent, or corrupt, because the problem has only gotten worse despite all of the options available to them like the manifold sensible suggestions found in this thread. I'm reading these threads and SE hasn't implemented any of these techniques. After multiple years the dev team has done NOTHING. They're doing NONE of the things suggested here and most players have either stopped caring or stopped playing. I'm joining that second distinction after playing for two months. The last time I was subjected to this much goldseller spam was on free to play games. Contemptible, and in my opinion, unacceptable.
