Warbands doesn’t mean account wide ignores necessarily, because it’s a retail thing and not a classic thing.
Final Fantasy and most likely other games are updating their forums to keep up with technology and evolution. This forum needs to evolve into the modern era with account wide ignores.

This was a late edit after lock I hope it gets read and counts towards the feedback but I think a few things need to be added into the code of conduct especially spreading rumors and false information in the forums to cause unrest and chaos especially when it divides the community.
