It may have been accessible, but when Brisc says:
He is talking about the SART/NRTA in mainland China, which is the regulatory body that requires publishers to obtain a license for video games to operate in mainland China. Presumably Serenity is the licensed version of the game. If CCP Games does anything to skirt around the unlicensed content, the SART/NRTA (edit: technically the Ministry of Commerce issues the license) has economic leverage to force CCP Games to comply by revoking the Serenity license (losing money in the Chinese market) and/or further action (ex: GFW). This has long been a core strategy of the CCP (Political Party) to both entice foreign investment and influence foreign companies.
Just because the GFW in practice has let folks connect to TQ servers and unlicensed games in the past, does not mean TQ has been blessed by the Chinese government.
edit: I am very sorry you and others are in this predicament, I am sympathetic to getting the problem fixed. I would not hold my breath though.
