Anonymous comments can end up in the SPAM folder.
I'm not a huge fan of them.
So far, my experience with Anonymous posters have been bleak and rude and very unhelpful. I've found that the Anonymous people accuse me of being things I'm not, relishing the fact that since I can't tell who they are I can't return the favor other than pointing out their folly (which they'll ignore anyway). I've found that the Anonymous person to be something of a coward, refusing to put their name to a political position, preferring to hide in the shadow and think themselves clever for hiding so well.
If I ever post an Anonymous Trolling Comment of Little Worth, it's because I want to make a point of how foolish that troll's comment really is. Most of the rest of them I leave in the SPAM folder.
If you want to leave a comment, do so. But have the decency to put your name to it, especially if you're going out of your way to insult somebody. If you're insulting me, heh, I can laugh it off. I've survived middle school: I've heard worse. Insult someone else, you'll get called on it. But own up to what you write: you owe yourself that much. If you can't respect yourself to put your name to your opinion, how the hell should you expect us to respect you for it?
