There are people who will spend as much money as they need to obtain multiple accounts, subscribe to multiple VPN services to swap IPs frequently, borrow accounts, open up several checking and credit accounts and so on just to circumvent official action. It's 2017, and many of us know and have seen first hand that a ban is no longer truly a ban. Malicious players can be smart about it and it can take weeks to piece together all the evidence to even get so much as just one character temporarily removed far after the fact.

Hopefully these are some of the things Square Enix (and other game companies) look into in the future when implementing social environment controls in online games. As new as the work and technology that goes behind tracking and suspending or banning users is, it's already obsolete. We absolutely need a change.
