Considering that Square Enix is still learning in comparison to other companies that have run MMOs for longer I can definitely see them learning from this. In the future, they'll likely add even more countermeasures for such an issue.
They did have measures in place for everything else. This just wasnt an issue like it was in previous releases. I am atleast hoping it'll be a good learning experience for them. ¯\_(ツ)_/¯
