Don't worry about up/down votes. I've had very strange things with a large number of downvotes on a comment and then a very large number of upvotes one or two layers downthread. Presumably there are some bots/brigades that are trying to create a "good history" to try and pretend they are "organic". The bots/brigades don't care about anything more than the first layer.
