Do you go through your comments and find that one comment (or maybe more) where the commenter is either goading other commenters or even trying to goad you into an argument? What is your reaction? Here's my advice:

Don’t Feed The Troll

Trolls have existed since USENET was the Internet service of choice. Heck, I think they existed back before the Internet took off, when BBS's were the primary online communication services.

Troll tactics include attacking regular commenters, attacking authors, making out like the troll is a victim or a savior of some kind, making comments that require an angry response as the only kind of response suitable and other things that generally don't go with good conversation practices.

The best way to defeat a troll is to ignore a troll. A troll will not hang around and comment further if he or she does not get a response. I spotted a troll earlier today. He was an ugly critter. He was easy to spot. He didn't leave any kind of URL in the header of the comment. Trolls are notorious for not identifying themselves with anything but their first name or some strange phrase.

If you think you saw the troll, let me know. I want to make sure I'm not seeing things.
