It's very difficult to weed out the people who have a lot of gil who aren't legitimate players. Back around the start of ARR, a lot of legitimate players were making a lot of legitimate gil... but, a lot of RMT were making money the same way. What was SE's solution? They blanket suspended every single person over a certain amount of gil (the 'cap' changed depending on which server you were on -- legacy players were allowed to have more before being flagged). These suspensions were not permanent... they were pending investigation. A lot of legitimate players were stuck offline for a while waiting for their accounts to be investigated. I remember this very vividly because when I found out that was happening, I stopped trying to make money as fast. The RMT were banned but... at the inconvenience of a lot of legitimate players just trying to make gil. It's hard to know who is RMT and who isn't from a SE standpoint. It can seem obvious to us, but I'm really wondering what SE exactly tracks regarding social activity.
