Market bots are akin to illegal immigrant workers of the United States: they are now a staple of the workforce. There are those who want them to stay and those who want them to go. Buyers love it and sellers hate it. It takes about 10 minutes of research at most to know if one is a bot account yet SE does nothing about them. You can assume with near certainty that SE won't be taking action against them, ever, so don't even worry about reporting it. It's ironic how the bots are a major source of RMT and that is supposedly something SE really cares about. In my opinion SE doesn't mind the bots because bots make everything cheaper so it is very helpful for the casual and new player base, and may keep them paying for subs longer than they would if bots weren't around.
