We feel that the word smurf should not be banned.
1. It's freedom of speech
2. It's all in good fun
3. It hasn't been used to offend by almost all users.
We think it should be unbanned. However, we are fine with Nope being banned as that is much more stern and has been used a few times to offend.
I don't have a strong feeling on it one way or another. However, I've never really liked the "freedom of speech" argument that claims you can say whatever you want, wherever you want, without any consequences or criticism from others. Freedom of speech doesn't mean you can say whatever you want, wherever you want without consequence. Freedom of speech means that the government in no way can limit your freedom to say whatever you want. The government cannot make any laws that limit your speech. The government cannot punish you for that speech.
Furthermore, no one can keep you from saying whatever you want. However, the medium in which it is said can have consequences. If you think I am wrong, go to your boss and tell him "Fuck you" to his face and see how quickly the freedom of speech claim will let you keep your job. He can't keep you from saying it. He can't have you arrested for it, but it's completely within his rights to fire you..
In the same vein, a website doesn't have to allow you to say whatever you want. And I am not speaking specifically about WWE Forums and I am not speaking on behalf of them either. This is just my own viewpoint on the manner. There's no obligation to let you say whatever you want simply due to the first amendment.
