I've never reported anybody (except egregious spammers, defined as "bots that are so obviously not people that I pull the adjective 'egregious' out of my drawer to apply to them") but I only attract low-level trolls. Most of whom, for reasons I've never determined, are "men rights" or "women are just MEAN" sorts, complaining about something I've written about my first or second wife. I've been trolled more often for my "Chats with Deb" than any other category — and yes, I realize that random statistics alone would cause that to happen. But still!
