People are paid to post here. And the people who pay them to post are CHINESE. It seems like the CHINESE are paying them to post more often, or paying a different group of people to post in addition to the ones they were paying before or it's a different group of CHINESE paying a different bunch of people to post different things.
But that's how it goes with CHINESE. Lie, cheat, steal. Bribery and blackmail.
