I know this is old, but saw this and was somewhat disturbed by it.
This seems to be a highly discriminatory rule, seeing as there are players from all around the world, and languages vary. Other languages being said are as much spam as the English comments on there anyway. I've been on many mmos where the moderators speak a primary language, and everyone was allowed to speak their own language.
If they needed a mod's help, it wasn't their fault if they didn't speak the same language, not much you can do. If members didn't understand the other language, they could just mute the player and move on instead of griping. In fact, one server was mainly Mandarin Chinese, and English players weren't bashed out of talking in the main chats. If it was the same here, I'd bet all the English speakers would be up in arms if only Spanish speakers, or Polish speakers could use the general chat.
It seems somewhat disturbing to me that people so readily found this acceptable on here. Even if this was produced in an English-speaking country, it was distributed on the internet, which is worldwide. I'm sure this makes it easier for the moderators (albeit I haven't seen any on the game in quite a long time), but that doesn't make it right.
Are you going to say it's secregation that the workers in a bank in america or Australia or england can't deal with customers that don't speak their language?
I understand the thought behind this, but I don't think it really doesn't hold ground with the situation at hand. When you're in a certain country, you are expected to know its language to a certain extent of course. You go up to someone in a store and start speaking Polish in California you're going to have a very confused employee. But this game is beyond just one country, it's far more diverse than that. Anything that dips its fingers in the international community has to accept that all language needs will have to be met, that's how the game goes. Those that don't play it are typically called discriminatory and lose the respect of the international community.
Edit: I find this especially contradictory when the forum is in 2 different languages. :/
