So right on all counts. I've been blogging for over 9 years (and a YT producer also) who has dealt with Trolls for too long. Like you, I might give them one measured response, then kick them to the curb. There is no room for negativity in my comments. Debate or discussion, now that is completely different, as long as it is constructive. Keep hammerin' on 'em... they will disappear eventually. u/v
