Send enough traffic over an IPSec tunnel in a short enough period of time, and expect it to be suddenly blocked one day, only to work again in just a few days.
This. It's totally arbitrary. Also it's a two-tier system, where many things are easily proxied around, while some sites (pornography, Falun Gong, Tian'anmen) can't be.
I think mostly the point is to inconvenience and be protectionist rather than block. Sure you can get on twitter if you really want, but your average Joe in China doesn't want to bother figuring out proxies just to get some stupid cat picture, so they turn to Weibo or some wannabe-twitter site like that instead.
