I just came to the library to get a few cards and got asked to be friends by one person 20 times, there has to be a way to stop them for doing this. I have a full friends list and when you say that they get mad. Give me the option to say no and mean it!
If you switch realms, whoever is harassing you probably won't know what you did. Even if he did, he probably won't be able to find you to continue harassing you.
I know and when you tend to be a high level like over 20 and you come to WC for a quest or a color change you get asked by many low levels to be their friends and of course I say no because I am not power leveling them and getting them to places they are not ready to go yet.
