Here's at least one source http://www.chinadaily.com.cn/kindle/2014-10/02/content_18692... Although I appear to be wrong that it was specifically what caused the block.

I'd be interested to know the source of your claim that facebook wouldn't be allowed if it complied fully with Chinese law?

One, this article was published years after Facebook was blocked in China so it can't be the cause of the block. Also, China daily is a propaganda outlet. https://en.m.wikipedia.org/wiki/China_Daily

It's literally run by the "Central Propaganda Department".
