The only thing I've managed to acquire by leaving anonymous comments on is negative comments and insults, so that option has to go. I admit that my posts are at times snarky and sarcastic, but at no point do I ask for unsolicited nastiness. If you've ever read H.L. Mencken, you understand the basis upon which much of my writing style is formulated. If you don't, then you're totally missing the point altogether.
I've hit the same situation here which many of you have already reached on your own blogs with your own unfortunate troll problems. Henceforth, if you have no identity, you have nothing to say here in comments.
