I've gotten emails from several people asking me why I stopped fighting with people in my Facebook comments.
The truth is, I still do it, but not as often as I was for a while. There was a month or two period when I was going all in, responding to all of my haters, laying traps for them, getting them to say things they'd regret later... it was a big hit!
The engagement kept growing... people were coming to my page just to check out the comments and watch me argue with people. Maybe you were one of them.
