From Reuters:
Chinese police arrested thousands in a drive against Internet pornography throughout 2009, officials said, vowing a deepening crackdown that critics say is being used to tighten overall censorship.
The Chinese government has run a highly publicized campaign against what officials said were banned smutty and lewd pictures overwhelming the country’s Internet and threatening the emotional health of children.
Chinese police said late on Thursday the crackdown on Internet pornography had brought 5,394 arrests and 4,186 criminal case investigations in 2009 — a fourfold increase in the number of such cases compared with 2008.
