- Accounts receiving disciplinary action for RMT site advertisements: 6,154 accounts
- Accounts receiving disciplinary action for illicit activity: 156 accounts
- Action Details: Termination from FINAL FANTASY XIV: A Realm Reborn

Ok, forgive me for being sceptical here, but what exactly is 156 Accounts receiving disciplinary action for illicit activity?
Are these teleport/speed hacker gatherers? People selling gil? I'd really like to know, because 156 seems like a VERY small figure when you think about the number of servers there are.
Heck, I am pretty sure we could almost give you 156 teleport/speed hacker gatherers on Diabolos alone.

I know I personally have reported at least 30 of these in the last few weeks.
