Did I tell you it never helps your karma to go against the wise and just moderators? I used to have this signature, which I'm retiring now.
Overrated, Troll, and Flamebait mod points are not to be used towards posts you disagree with. That would be censorship.
I've got good karma, and I wonder why it hasn't gotten worse. Ever since I used this signature to protest those moderators who abuse the system, I noticed that it's harder to get modded up even when I write a post that deserves it. My post is apparently still visible because it receives a number of responses, and the users who responded to me got modded up. The signature offends prospective moderators, who would have modded up the post if the signature was not there. Furthermore, it actually encourages some moderators to use the "overrated" mod against my posts just for the added irony.
It looks like my education campaign, or moderation fairness campaign, achieves exactly the opposite of its intended purpose. Rather than helping more moderators become more aware of their responsibility, it actually encouraged and attracted more abuse. This signature is futile. I guess the removal of this signature means I'm receding to the moderator overlords.
Slashdot is a democratic forum where voices deserve to be heard? You've gotta be kidding. The same people who side with freedom of speech is doing the censorship themselves.
