If Taiwan has freedom of speech, why does any question with wording ''reunification'' or ''reunite with mainla?

Yahoo has a computerized system to process complaints. If enough complaints come in, even if they are from hundreds of troll accounts controlled by one person, then the question gets deleted. A real person at Yahoo never saw your question. "We Never Left" is the troll queen in Yahoo's China and Taiwan forums. He has many other aliases including "Matt of Asia", "Craftylass", and "Lim Yuan".
