I believe they told people how to get around them in the official FAQ rather than remove the IP blocks.
NÃ£o proÃba Brasil por favor, eu imploro a vocÃª
Brazilians can get on the game, I don't think they removed the full restrictions.
If there is a wide scale cyber-attack on EME and it's coming from another region, then yes, EME should bar that region from accessing NA Tera.
It is curious that these issues have hit like this now that there is no region lock in place.
My one issue with locking down the region again would be that a chunk of my friends who play aren't in the correct region and have been playing since beta. If they did get serious about locking down the servers, they really should make special concessions for long-time players from other regions.

Ban everything but North America ... Canada, US and Mexico ... go go go.
