Three Baidu employees have been arrested in China over accusations of being bribed to delete content from the Baidu forums. The accusation is that these employees along with a fourth one, who was also fired but not arrested, deleted posts that companies or individuals wanted removed, critical reviews for example.
The four are said to have made some "tens of thousands of yuans," which adds up to some thousands of Euros or dollars, from the bribes. It's no wonder that an internet culture built on censorship, of the government kind, would breed this type of behavior, not that this is happening only in China.
But it is easier for companies to try these things and for employees to charge for it when the government does the same and when the same employees censor things, for free, for the government.
This is not the first time that employees were caught over issues like these, but it was the first time the police was involved, due to the relatively large sums of money.
