The question is：Did admin remove those comments because they felt that it was all spam coming from the same IP address or did Worlda remove those comments of their own accord?

Some clarification from the admins would be nice here.

What's even more bizarre in that instead of merely posting fake positive reviews, even some of the negative comments appeared to be written in Chinglish and they too, also seem to have disappeared. Worlda may have tried to cover their tracks once again, but this time they have overcompensated and f**ked themselves with their own cock, so to speak. Their attempt at the removal of evidence has effectively provided this board with more evidence.

I've heard that this is a common wumao tactic on Chinese BBS sites, where the wumao will write comments representing both sides of an argument, even putting two alias into battle to create a false illusion of genuine discussion which is eventually swung in the way of the government propaganda department. For a private company to be imitating such wumao style tactics does seem very strange indeed.

Anyway, my question to all teachers is: Do you really want to work for a company that has to resort to those kinds of dirty tactics in order to promote itself?
