@IfrianMMO I wouldn't say the matter is settled. Other games have backtracked on censorship, such as Tera with Elins. Changes don't happen over night.
An in game poll can work as the alts can be negated by the sheer number of players. There is also the option to limit it to one vote per IP or Mac address; it should be possible to check what IP addresses an account has used in the past if going that route. Obviously limit it to accounts before the poll was implemented and perhaps add a level requirement of 50 or 70.
@Scerms77 Some people would prefer to play the version that they are meant to play (technically is against the ToS to play JP outside of Japan, even if Sega turns a blind eye to it). Some people want to support the global version with monetary purchases but can't do so in good conscience with the current state of the game (I am in this boat). There are also some fears of the censorship affecting JP somehow, like it may affect NGS somehow. So plenty of reasons why some people continue to fight against censorship.
