More than 7,000 accounts banned or suspended.

Not only has FF XI announced that they've banned or suspended a large number of accounts, but they also gave the breakdown of when and how many they banned for each action.

We would like to report the termination today of multiple accounts held by players involved in the usage of third-party tools or cheats, or engaged in RMT (Real Money Trading) activities.

Based on the results of our investigation, around 6,860 PlayOnline accounts were terminated while around 990 accounts were temporarily suspended.
Additionally, we have increased the number of mass bannings against certain PlayOnline violations in order to prevent illegal acts.

To see the breakdown of bannings, check out the announcement on FF XI's main site.
