I can only assume that all of the level 80 bots are "legit" and actually paid for Shadowbringers and/or a level/story skip to not have been banned for so long, which would mean they're actually pulling in enough RMT sales to support their sub fees and other expenses.

Which further makes me think SE needs to put more emphasis on punishing the buyers then going after the ones generating the gil, because you can never truly solve that problem as long as those slash and burn ARR gil farmers exist. You can, however, scare people into not wanting buy gil in the first place.
