Greetings, @meno. I have even become a follower of a certain young man who strongly disagreed with me on one of my post. We had a very civil interchange of views and he ended up telling me "that's how you earn a follower."
But, I have also had my fare share of ugly interchanges that ended up in unfollowing and me biting my tongue and fingers to avoid writing something nasty.
No much at stake, though. What we are seeing with @kafkanarchy84 is a totally dangerous level. We should not be having that kind of crap here.
