Sina Weibo Censoring "Gu" - Probably Not Targeting Google

I noted in a previous post that a search for "Guge" (谷歌 - Google's name in Chinese) on Sina Weibo returns a censorship notice. As the screenshot shows, Sina Weibo is also censoring searches for just "Gu," so everything with that character is getting blocked. Seems like Google is just collateral damage.
