the first pic you show is one of the bannable offenses, and in that case if you want him banned you bring attention to it. when a mod sees it directly they can immediately take action and when they don't you report it and they take action for the second, that's a wasted effort on your part to start something. that is obviously trading co-op runs, not accounts. no need to stir the fire unnecessarily. I trade runs all the time and many others do as well because that's what co-op is for.
