BA shows that we fail as a Community (big time)

[Hyperia]

This is right on the money. When you develop any kind of multiplayer game, you need to know how to direct your community. This can be as simple as providing rewards to incentivize people to run old content (see: the daily roulettes), but it also covers the application and use of systems meant to discourage abuse and promote teamplay. Honestly, Square Enix should have seen these BA problems coming from a mile away. You lock a limited number of portals to a super-hard piece of content that will only be cleared with pre-made groups, fill it with enticing rewards, and then drop it smack dab in the middle of another piece of content (Eureka Hydatos) that is comparatively more pug-friendly and casual-friendly, and then fail to add any systems to discourage abusing said limited number of portals, and you've got a recipe for disaster.

They updated the TOS the moment they realized what BA was going to do to the community in NA/EU.

It's more that they knew what people were like so they updated the TOS to try and encourage players to get along for the content.
This hasnt been succesful as a deterant by the looks of it.
