Hey Troy, long time watcher from YouTube, are you aware of the "mute" button on steem? I've just noticed it myself. Maybe a tip to making the trolls talk to themselves. It's not a block button but if all viewers want to remove troll comments from their screens, it's an idea.

Keep strong and keep up the great videos. Some people just way too much time on their hands.
