People who look forward to, and eagerly engage in, the kind of food fight we had yesterday should expect a banning. It's very easy to know when you've pushed into too far. Can you not fit half a sentence onto a line? You've gone too far. Is a third of a 300-plus post thread dedicated to your war with someone whom you've never met? You've gone too far. Have you been reduced to name-calling and rudeness? You've gone too far.
When you're deploying your sarcasm to hurt people, you've gone too far. When you're just getting your rocks off, you've gone too far. When you are speaking to people over the internet in a manner which you would not speak to them face to face, you've gone too far.
It's easier than you think to walk away. It will bother you for about ten minutes. You'll have a beer, and all of it will fade away.
Let it go--before it let's you go.
