You want my opinion? This will be about as effective as throwing gasoline on a fire. It's the equivalent of giving them an award.

p.s. your gay

Dude, at least I can write proper grammer. I think you meant to say "You're gay", which is true. I am very happy.

But thanks for your opinion. You are probably right. I didn't think it would shame them at all, but I didn't consider that it would actually do the opposite. Good point.

It will also mean that user must be authenticated to post a comment...
I'll never post comments if I have to login before doin it

The best way to deal with trolls is ignoring them. I've always wanted to implement a system where users who troll are marked as such by the admin. Future posts, due to security restrictions, allow the troll to read his or her own, but it marked as "READ:DENIED" for everyone else. Therefore, the troll will wonder why no one is responding and simply go away.

And I'm actually all for logging in to comment. I've seen some larger sites do it and actually improved their comment sections. Me? I've got 30 regular readers, so requiring sign up would kill the 2 comments a week I get (on par with posts, I guess).

The whole anonymity online thing is what breeds trolls and trollish behavior. That's why I use my name when posting - keeps me somewhat honest.

Does it come in green?

While I'd rather not debate your gayness, I agree that it will probably do no good, or more harm than good.
That being said, I'd LOVE to see this become part of subText!

I also second Simone; no comment if login required... Mostly for the reasons Robb indicated; the few readers I have will probably NEVER comment then.
