Just saying, in the early years of wow (and I don't think people who are asking for "blizz-like" so much that they sometime become silly about it, was there) you just had to make a request MJ and say something like that :
"Hello MJ,
I get regularly wisp by people who are saying I have the same name as a pornstar. I am starting to have a problem with that. Is there a solution?
Thank you"
And you get a rename at your next connexion...
Blizzlike is very important for things like spells effects, boss stats and everything who touch the gameplay. But don't became crazy (stupid) about it and let people change their name.
