I am still small enough that I am able to read every comment, and will delete toxic comments as needed and even try to moderate some discussions. I suppose as I get bigger I will start using the feature that allows you to review posts with certain words, etc. On a side note, I don't think returning to conversations necessarily equals increased views. I know when I am clicking a link to return to a discussion the video automatically pauses. Even still, since you are logged in, they are able to track that you are returning to the same vid over and over again and may adjust the view count accordingly.
