I tend to look at the big picture. There is a recent trend on YouTube to inflate the upvote count of certain posts, probably using a bot. This will sound political, so correct me if I'm wrong by providing obvious counter examples, but the upvote count inflation appears to be for liberal posts only. Here is the most recent blatantly obvious example... https://youtu.be/wKSOXFF4TPw...

Similar amps from TI and Maxim seem to have the same issue. Here's one fix: https://www.dropbox.com/s/tdzs1ydi7quzbs7...
