I think a big part of it is bots automatically upvoting and downvoting based on state department talking points. I one time on a small sub about mall swords posted with thr ironic title of something like, "china bad" and I got the record for upvotes on that sub. So some bot noticed the post, then just dumped more upvotes on my post than there were peopel that used thr sub. It's eazy to see that if I was liberal how that could cook my noodle into posting more anti china stuff
