I had started using Wikipedia at the age of about 16, before Chinese government imposed censorship on it. After one or two years living behind the 'Wall' and using proxy, I came overseas but found more problems with Wiki. I have witnessed suspicious accounts trying to modify sensitive contents and absolutely ridiculous (from both left and right wings) fights over controversial issues. It is a painful reality to face, but I guess the only way out is to join the 'war' or conversation, whichever you like.
If this seems dull, that's bcoz of the racism I've encountered here on Wiki. Most ppl just assume a Chinese growing up in mainland China must be poorly educated and 'fen' all the time.
Btw, I like Oxford comma and shall use it whenever I write in English (it's not allowed in proper French, sadly).
