Has anyone else noticed censored google trends in the us? I've noticed at least one regarding SHTF dissappear. Is anyone aware of or keeping track of google trends that dissappear?

What do you mean by disappear?
I get results when searching [SHTF] on google trends.
http://www.google.com/trends?q=SHTF

I believe it was tshtf but when I tried it I got nothing. SHTF doesnt bring up the original result that I got anyways. The graph that I got at the time was increasing steadily over time and it began before the one that shtf shows.
